I follow your video all the time. I used cypress to automate my project, that has many limitations. I found PlayWright is much better to open multiple tabs. Waiting for your video: 1 upload files from a folder 2 verify downloaded file 3 how to split test cases in multiple workers. Great job! really appreciate your hard work
Hi Raghav, I have done first 3 tutorials on Playwright so far and got 10/10 on all 3 quizzes :) Thank you so much for taking the time and effort to explain the automation tool in simple and easy way.
thank you so much! you video is the ONLY one I can find that start from scratch and mentioned EVERY little details for a totally clueless beginner. Also, love the way you make your keypoints in one page for us to screenshot for later use.
Thank you so much for your tutorials - These are the best tutorials i have used so far I am new and beginner to Playwright and just by watching your tutorials i have developed interest in learning the tool Thank you so much again Lots of Good Wishes
Hi Raghav. Thanks for your lessons. I currently facing one issue in testing block I can not see any test to execute through play button. Instead it’s showing no tests have been found in this workspace yet can please help me on this
Shiva Check your command, in the path of the test file try giving single forward slashes File Naming: Ensure test files are named with .spec.ts, .spec.js, .test.ts, or .test.js suffixes (e.g., example.spec.js). Test Structure: Verify that your test files are structured correctly. A basic example: const { test, expect } = require('@playwright/test'); test('basic test', async ({ page }) => { await page.goto('example.com'); expect(await page.title()).toBe('Example Domain'); }); Playwright Installation: Ensure Playwright is installed: npm install @playwright/test Configuration File: Check for a playwright.config.js or playwright.config.ts file in the root of your project. Run from CLI: Execute tests directly via the command line: npx playwright test IDE Settings: If using an IDE, ensure its Playwright extension is properly configured. Restart IDE: Sometimes a simple restart can resolve detection issues. Update Dependencies: Ensure all dependencies are up to date: npm update @playwright/test -
Hello Raghav. I need to say that you're very good teacher. Very clear and simple to understand. I have one question ... why, when I run any tests from Terminal, using (for example) command: npx playwright test .\tests\example.spec.js ... I got message : Error: No tests found ... ?
Hi, If you are running tests in Playwright using the command npx playwright test, you need to make sure that your tests are organized in a certain way so that Playwright can discover and run them. By default, Playwright looks for test files in a directory named tests, and for test files that have a name ending in .spec.js or .test.js. So if your test file is named example.spec.js, make sure it is located in a folder named tests in the root of your project directory. If your test file is located in a different directory or has a different name, you can specify the file or directory using the --test-match option when running the npx playwright test command. For example, if your test file is located in a directory named my-tests and has a name ending in .test.js, you can run the test using the following command: npx playwright test --test-match="./my-tests/**/*.test.js" Make sure to specify the correct path to your test file or directory. If you are still getting the error "No tests found", make sure that your test file contains at least one test case that is defined using the test function from a test runner such as Jest or Mocha. For example: const { test, expect } = require('@playwright/test'); test('example test', async ({ page }) => { await page.goto('example.com'); expect(await page.title()).toBe('Example Domain'); }); This test case uses the test function from the @playwright/test package to define a test named "example test". Make sure that your test file contains at least one test case defined in this way.
Thanks, Raghav. Scored 9/10. It would have been great if the recording was made on a picture quality of more than 720p. Not sure if there is a setting on your side whilst recording that can be adjusted to provide better quality? But content is good as usual :)
Hi Ragav! Thank you for posting detailed videos.They are very helpful for anyone starting to learn Playwright with no background. I want to know why some tests fail in "webkit" or "firefox" browser libraries but pass with just chromium.However the error shows that page timed out, in the terminal we see the reason is "the webpage has been blocked by our organization".If that's the case we shouldn't be able to run the testcase in chromium as well, right?
Anushka Here are potential reasons for the inconsistencies you're experiencing with Playwright tests across different browsers, along with troubleshooting steps: 1. Browser-Specific Rendering or Behavior: Websites might render or behave differently in different browsers due to varying JavaScript engines, CSS implementations, or browser extensions. Inspect the website's behavior in each browser manually to identify discrepancies. Adapt your tests to handle browser-specific variations using conditional logic or Playwright's browser-specific selectors and actions. 2. Browser Configuration or Settings: Check for inconsistencies in browser configurations like privacy settings, content blocking, or proxy settings. Ensure consistent configurations across browsers using Playwright's browser launch options. 3. Playwright Version or Browser Compatibility: Update to the latest Playwright version for compatibility fixes. Consult Playwright's documentation for known compatibility issues between specific browser versions and Playwright. 4. Network Issues or Firewall Rules: Investigate network restrictions or firewall rules that might selectively block certain browsers or websites. Review organization-wide policies and collaborate with IT if necessary. 5. Timing Issues: Adjust timeout settings for page loads or actions to accommodate potential differences in loading times across browsers. Use explicit waits for specific elements or conditions to ensure tests proceed only when the page is ready. 6. Debugging and Troubleshooting: Enable verbose logging or debugging in Playwright to gather more information about browser interactions. Isolate the problematic tests to narrow down the root cause. Test in different environments to rule out environment-specific issues. Specific to the "webpage blocked" error: Double-check organization policies and firewall rules to understand the exact restrictions. Check if Chromium has any exceptions or bypasses for these restrictions. Consider using a VPN or proxy to temporarily bypass restrictions for testing purposes if allowed within your organization.
Hi Raghav, thanks a lot for wonderful content, i am getting below error, seems command is correct and folder is also present : PS C:\Playwright_Test> npx playwright test .\tests\example.spec.js Error: No tests found. Make sure that arguments are regular expressions matching test files. You may need to escape symbols like "$" or "*" and quote the arguments.
Chandan There are other comments with the same issue... pls check if any of those solutions work for you.. else you can check this: 1. Check Test File Path: - Ensure that the path to your test file (`example.spec.js`) is correct. - Verify that the file exists in the specified location (`.\tests\example.spec.js`). 2. Regular Expressions and Special Characters: - The error message suggests that you might need to escape special characters like "$" or "*". - Make sure your test file path doesn't contain any special characters that need escaping. 3. Quoting Arguments: - If your test file path contains spaces or other special characters, consider enclosing it in double quotes: ``` npx playwright test ".\tests\example.spec.js" ``` 4. Check File Content: - Ensure that your `example.spec.js` file contains valid test cases. - Verify that the test cases are correctly defined using Playwright's syntax. 5. Update Playwright: - Make sure you're using the latest version of Playwright. Update it if necessary: ``` npx playwright update ``` 6. Run with Absolute Path: - Try running the test with an absolute path instead of a relative path: ``` npx playwright test C:\Playwright_Test\tests\example.spec.js ``` 7. Check Test Naming Convention: - Ensure that your test functions follow the correct naming convention (e.g., `test('should do something', async () => {...})`). 8. Check Test Configuration: - Verify that your test configuration (e.g., `jest.config.js` or `playwright.config.js`) points to the correct test files. 9. Debugging Logs: - If the issue persists, check the debug logs for more details: ``` npx playwright test --debug .\tests\example.spec.js ``` 10. Reinstall Playwright: - If none of the above steps work, consider reinstalling Playwright: ``` npm uninstall -g playwright npm install -g playwright ``` Remember to adapt these steps based on your specific setup and requirements. ..
Hi Raghav, i cant see the details from code in the test report. This cannot be opened any further. I only see the main fields with the text and steps. Is there another way to show us how to make a POM and especially in combination with the recording function?
Ahmed When using Playwright for testing, you can explore test reports in a few ways: 1. HTML Reporter: - After your test completes, an HTML report is generated. It shows a full breakdown of your tests, including browsers used, test durations, and individual steps. - You can filter the report by browsers, passed tests, failed tests, skipped tests, and flaky tests. - Clicking on each test allows you to explore errors and view each step of the test 2. Command Line Report: - You can see a concise report directly in the terminal using the `list` reporter. It prints a line for each test being run. - To enable step rendering, you can pass the `printSteps: true` configuration option¹. - Example usage: ```bash npx playwright test --reporter=list ``` 3. Browser Window Report (Debbie Codes): - Run the following command to open a browser window with a detailed report of your tests: ```bash npx playwright show-report ``` - This report includes information about browsers used, test durations, and individual steps Remember that Playwright's built-in reporters provide different levels of detail, so choose the one that best suits your needs. If you're interested in creating a Page Object Model (POM) in combination with the recording function -

I am using visual studio code and trying to learn playwright using C#. I want to run the code in HEADED mode and used command set HEADED=1 dotnet test but it is not running. Could you please help in this.
Ankita The command `set HEADED=1` is used to set an environment variable `HEADED` to `1`. This is correct. However, the `dotnet test` command is used to run unit tests in.NET, but it doesn't directly relate to Playwright or Headed mode. Check the Playwright configuration To run Playwright tests in Headed mode, you need to configure Playwright to use Headed mode. You can do this by setting the `headless` option to `false` in your Playwright configuration. In C#, you can do this by creating a `PlaywrightOptions` instance and setting the `Headless` property to `false`: ```csharp using Microsoft.Playwright; // Create a new instance of PlaywrightOptions var options = new PlaywrightOptions { Headless = false }; // Launch the browser with the options using var playwright = await Playwright.CreateAsync(options); ``` Run the tests Once you've configured Playwright to use Headed mode, you can run your tests as usual using the `dotnet test` command. Verify the environment variable Although you've set the `HEADED` environment variable, it's not necessary to set it explicitly. The `Headless` property in the `PlaywrightOptions` instance should be enough to run the tests in Headed mode. However, if you still want to use the environment variable, make sure it's set correctly before running the tests. You can do this by running the command `set HEADED=1` in your terminal or command prompt before running the `dotnet test` command. To summarize, you need to configure Playwright to use Headed mode by setting the `Headless` property to `false` in your Playwright configuration. Then, you can run your tests using the `dotnet test` command -
I love your videos, they're super helpful! Can I ask what tool you use to create the red squares in the video as seen at 2:30. I do lots of screen recordings when demonstrating bugs to my team and I would love to be able to bring attention to a section of the screen like that.
Question "Command to run with 3 workers in parallel" in the quiz, answers "npx playwright test --workers=3" and "npx playwright test --workers 3" are both correct and equal. Same with "Command to run on specific browser", "npx playwright test --project chromium" and "npx playwright test --project=chromium" are equal and will execute tests in chromium
Ashish End-to-End (E2E) testing is a comprehensive approach that evaluates the entire software system by simulating real-world user scenarios from start to finish. Here's what you need to know: 1. What is E2E Testing? - E2E testing ensures that the application works as expected from the end user's perspective - It covers the entire workflow, including the user interface, backend services, databases, and network communication - The goal is to validate overall behavior, functionality, reliability, performance, and security. 2. Writing E2E Tests as a Manual Tester: - Identify test scenarios: Understand the user stories and identify the critical scenarios. - Map the steps in each scenario: Break down the user flow into specific steps. - Perform manual testing: Execute the steps manually to verify functionality. - Automate the tests: Once you've validated the manual steps, consider automating them using testing tools or frameworks. - Add your tests to the continuous integration (CI) pipeline for regular execution Remember, E2E testing helps ensure that your application behaves correctly across different layers and interfaces, providing a seamless experience for users --
@@RaghavPal Thank you so much for such a detailed explanation. Thanks a lot on guiding on how to write and perform E2E testing as a manual and automation tester, this really helps me a lot in understanding E2E testing in a broader way.
@Raghav for me npx playwright test .\tests\example.spec. doesn't work. It shows an error "Error: No tests found. Make sure that arguments are regular expressions matching test files. You may need to escape symbols like "$" or "*" and quote the arguments."
Clive Please try by adding a single forward slash / in the path of file in your command, e.g.: npx playwright test tests/example.spec.js Here are a few things you can check to resolve the "No tests found" error: 1. File Naming: Ensure your test file has the correct suffix, such as `.spec.js` or `.test.js`. Playwright looks for these specific suffixes to identify test files⁴. 2. File Path: Double-check the file path you're providing. It should be relative to the root of your project. For example, if your test file is located in the `tests` folder, the command should be: ```bash npx playwright test tests/example.spec.js ``` 3. Escaping Symbols: If your file path contains special characters like `$` or `*`, make sure to escape them or quote the entire path. For example: ```bash npx playwright test "tests/example.spec.js" ``` 4. Configuration File: Verify that your `playwright.config.js` or `playwright.config.ts` file is correctly set up and points to the directory containing your tests. The `testDir` property should be set to the folder where your test files are located 5. Empty Test Files: Ensure that your test files are not empty and contain valid test cases. Playwright will throw an error if it doesn't find any test cases in the specified files -
Hi Debayudh, You can implement data-driven testing in Playwright by reading test data from external files like Excel or CSV, and then passing that data into your test scripts. Here's an example of how you can read data from a CSV file and use it in your Playwright test scripts: Install the csv-parser npm package using the following command: npm install csv-parser Create a CSV file containing your test data, with each row representing a separate set of test data. For example: username,password testuser1,pass123 testuser2,pass456 testuser3,pass789 Create a Playwright test script that reads the data from the CSV file, and then iterates through each row to run the test with each set of data. Here's an example of what the test script could look like: const playwright = require('playwright'); const csv = require('csv-parser'); const fs = require('fs'); // Read the CSV file containing test data const testData = []; fs.createReadStream('testdata.csv') .pipe(csv()) .on('data', (row) => { testData.push(row); }) .on('end', () => { // Iterate through each row of test data and run the test for (const data of testData) { describe(`Test with data: ${JSON.stringify(data)}`, () => { let browser; let context; let page; beforeAll(async () => { // Launch the browser and create a new context and page browser = await playwright.chromium.launch(); context = await browser.newContext(); page = await context.newPage(); }); afterAll(async () => { // Close the browser when the test is finished await browser.close(); }); test('Test Login', async () => { // Use the test data to fill in the login form await page.goto('example.com/login'); await page.fill('#username', data.username); await page.fill('#password', data.password); await page.click('#submit'); // Assert that the login was successful await page.waitForSelector('#welcome-message'); const welcomeMessage = await page.textContent('#welcome-message'); expect(welcomeMessage).toBe(`Welcome, ${data.username}!`); }); }); } }); This test script reads the test data from the CSV file using the csv-parser package, and then iterates through each row of test data to run the test with that data. In this example, the test script logs in to a website using the username and password from the test data, and then asserts that the login was successful. You can modify this example to read test data from other types of external files, such as Excel or JSON, by using the appropriate libraries or packages to parse those file formats.
Hello sir I'm a new suscriber I was trying to run a test on my Work tools however I may need to authenticate my Okta account otherwise the test will fail since it will not proceeded to the actual webpage, Is there any easy way to implement OKTA authentication to my tests, thanks and cheers
Hi Cherry, Yes, you can use the auth option of Playwright's Page.goto() method to authenticate with Okta. Here's an example: const { chromium } = require('playwright'); const expectWebauthn = require('expect-webauthn'); (async () => { const browser = await chromium.launch(); const context = await browser.newContext(); // Go to the Okta login page const page = await context.newPage(); await page.goto('example.okta.com/'); // Click the login button to trigger Okta authentication await page.click('#login-button'); // Wait for the WebAuthn/FIDO2 authentication flow to appear await expectWebauthn(page).toDisplay({ timeout: 30000 }); // Perform the authentication flow using a test credential await expectWebauthn(page).toAutoSubmit({ timeout: 30000, credential: { id: 'test-credential-id', rawId: 'dGVzdC1jcmVkZW50aWFsLWlk', response: { authenticatorData: 'test-authenticator-data', clientDataJSON: 'test-client-data-json', signature: 'test-signature', userHandle: 'test-user-handle', }, type: 'public-key', }, }); // Okta authentication should now be successful and you can proceed to test the actual webpage await page.goto('example.okta.com/my-account'); // ... })(); This example assumes that you have already registered a test credential in your Okta account and have its id, rawId, response, and type values. If you don't have these values, you can create a test credential using the webauthn-test-data library. Note that this is just a basic example and you may need to modify it based on your specific authentication flow and webpage.
Playwright doesn't have built-in libraries for Dynamics 365 .. but you can automate it using Playwright's general web automation features Dynamics 365 uses dynamic IDs, s, and custom UI components, which require careful handling with robust selectors (aria-label, data-*, etc.) and Playwright's support (frameLocator) For authentication, you can automate login flows or reuse tokens via Playwright's storageState. Example for logging in: javascript Copy code const { chromium } = require('playwright'); (async () => { const browser = await chromium.launch({ headless: false }); const page = await browser.newPage(); await page.goto('your-dynamics365-url'); await page.fill('input[type="email"]', 'your-email@example.com'); await page.click('button:has-text("Next")'); await page.fill('input[type="password"]', 'your-password'); await page.click('button:has-text("Sign in")'); await page.waitForSelector('#dashboard-selector'); // Interact with Dynamics UI here await browser.close(); })(); Playwright works well for Dynamics 365 with proper scripting but may require extra effort for complex scenarios -
No, Playwright does not have built-in libraries specifically for Dynamics 365. However, it can be used to automate Dynamics 365 applications by interacting with the web elements like any other web application. You'll need to write custom scripts to handle Dynamics 365's specific features and complexities.
Error: Project(s) "Microsoft" not found. Available named projects: "chromium", "Microsoft Edge", "firefox", "webkit" - Error while running the test on edge. added the name: 'Microsoft Edge', use: { ...devices['Desktop Edge'], channel: 'msedge' }, }, in the config file. What is causing this error
Sridhar The error message "Error: Project(s) 'Microsoft' not found. Available named projects: 'chromium', 'Microsoft Edge', 'firefox', 'webkit'" indicates that Playwright is unable to find the project named "Microsoft" when you're running your tests on Edge. This error occurs despite having the following configuration in your file: ``` name: 'Microsoft Edge', use: { ...devices['Desktop Edge'], channel: 'msedge' }, ``` This suggests that there might be a mismatch between the project name used in your test script and the one defined in your configuration file. Here are some potential causes and solutions for this error: *1. Inconsistent Project Names:* * Ensure the project name used in your test script and the configuration file matches exactly. * Verify if you're accidentally using "Microsoft" instead of "Microsoft Edge" anywhere in your code. * Double-check the spelling and case sensitivity of the project names. *2. Outdated Playwright Version:* * Make sure you're using the latest version of Playwright. Older versions might have different project names or require specific configurations. * Update your Playwright version to ensure compatibility and bug fixes. *3. Incorrect Configuration Syntax:* * Double-check the syntax of your configuration file, especially around the project name and `use` properties. * Refer to the Playwright documentation for the correct syntax for configuring projects. *4. Missing Browser Binaries:* * Playwright might not have downloaded the necessary browser binaries for Microsoft Edge. * Run `playwright install --with-edge` to download the required browser binaries. *5. Playwright Bugs:* * In rare cases, there might be bugs in Playwright affecting project recognition or configuration. * Check the Playwright bug tracker for any reported issues related to Edge project configuration. * If you suspect a bug, consider reporting it to the Playwright team with a detailed description and test case. *Here are some additional tips:* * Share your test script and the complete configuration file for further analysis. * Provide the version of Playwright you're using for specific troubleshooting steps. * Consult the Playwright documentation and community forums for assistance with your specific use case. By systematically analyzing the error message, exploring the potential causes, and implementing the suggested solutions, you should be able to resolve the "Error: Project(s) 'Microsoft' not found" issue and successfully run your Playwright tests on Edge.
Ben It's not uncommon to encounter differences in test behavior across different browsers when using Playwright. Let's explore some potential reasons for the discrepancies you're observing: 1. Browser-Specific Issues: - Firefox: Playwright tests may fail in Firefox due to various reasons. Some common issues include: - Network Logs: Network logs might not work out of the box for `playwright-firefox`. You can try specifying `ignoreHTTPSErrors: true` while creating a new context to enable network logs - Missing Dependencies: Ensure that all dependencies are installed. You can check the [Playwright CLI documentation](playwright.dev/docs/cli) for details on required dependencies - Webkit: You mentioned that Webkit fails with errors like "Element out of the ViewPort." This could be due to differences in rendering or viewport handling between Webkit and other browsers. 2. Flakiness and Race Conditions: - Flakiness in test results can occur due to race conditions, timing issues, or asynchronous behavior. Here are some things to consider: - Await Statements: Ensure that you're using `await` correctly in your test code. Missing `await` can lead to unpredictable behavior. - Dependencies: Double-check that all asynchronous operations (e.g., network requests, element interactions) are properly awaited. - Parallel Execution: When running multiple tests with multiple workers, there might be race conditions. Consider using proper synchronization mechanisms (e.g., `Promise.all`, `waitFor`, etc.). 3. Debugging Techniques: - To diagnose the issue further: - Set the `DEBUG=pw:api` environment variable to see detailed logs when Playwright interacts with the page - Inspect the failing test cases and look for patterns or commonalities in the failures. - Consider isolating specific test cases to narrow down the problem. 4. Storage State Reuse: - You mentioned reusing the storage state from login to complete other tests. Ensure that the state is correctly maintained across tests. - Verify that the login state is consistent and not causing unexpected side effects. 5. Viewport and Element Visibility: - For the "Element out of the ViewPort" issue, check if the viewport size differs between browsers. Adjust the viewport size if needed. - Verify that elements are consistently visible and interactable across browsers. Remember that cross-browser testing is essential to ensure robust test coverage
Sure, you can see the execution time of steps in the Playwright test report. The test report is a file that is generated after you run your tests. It contains information about each test, including the execution time of each step. To view the execution time of steps in the Playwright test report, you can use the following command: ``` npx playwright test --report playwright-report.html ``` This will generate a file called `playwright-report.html` in the current directory. You can open this file in a web browser to view the test report. The execution time of each step is shown in the "Steps" section of the test report. The time is shown in milliseconds
sir i got an error when i run the command "npx playwright test .\tests\example.spec.js" the error is "Error: No tests found" but when i run "npx playwright test" the commands runs successfully
Hi Saad The error "Error: No tests found" means that the Playwright test runner cannot find any tests to run. This can happen for a number of reasons, including: * The test file does not exist. Make sure that the test file exists and that it is in the current directory. * The test file is not a valid Playwright test file. Make sure that the test file is a valid Playwright test file. A valid Playwright test file must have the .spec.js extension and it must contain a function that is annotated with the @test() decorator. * The test file is not included in the test suite. Make sure that the test file is included in the test suite. The test suite is a list of files that are to be run by the Playwright test runner. You can specify the test suite by using the --suite option. Here are some steps on how to fix the error "Error: No tests found" in Playwright: 1. Make sure that the test file exists. 2. Make sure that the test file is a valid Playwright test file. 3. Make sure that the test file is included in the test suite. If you have followed all of these steps and you are still getting the error "Error: No tests found", you can try searching for help online. There are a number of forums and websites that can help you troubleshoot this issue Here are some additional tips for running Playwright tests: * Use the --suite option to specify the test suite. This will allow you to run a specific test suite from the command line. * Use the --watch option to run the test suite continuously. This will allow you to see the results of the tests as they are run. * Use the --headless option to run the tests in headless mode. This will allow you to run the tests without a graphical user interface. I hope this helps

Sourav The error message you're encountering, "No tests found," is a common issue when running Playwright tests. It typically occurs due to configuration or path-related problems. Let's troubleshoot this together! Here are some steps you can take to resolve it: 1. Check Your Test File Path: - Ensure that the path to your test file (`example.spec.js`) is correct. - Double-check that the file exists in the specified location (`.\tests\example.spec.js`). - Make sure there are no typos or missing directories in the path. 2. Use Correct File Paths: - When specifying the test file path, use forward slashes (`/`) instead of backslashes (`\`) to separate directories. - Example: ```sh npx playwright test ./tests/example.spec.js ``` 3. Quotes and Special Characters: - If your test file path contains spaces or special characters, enclose it in double quotes. - Example: ```sh npx playwright test "./tests/my test file.spec.js" ``` 4. Escape Symbols: - If your test file path contains symbols like `$` or `*`, escape them using a backslash (`\`). - Example: ```sh npx playwright test "./tests/my\$test\*file.spec.js" ``` 5. Check Test File Content: - Ensure that your `example.spec.js` file contains valid test cases. - Verify that you have defined test functions (e.g., `it`, `test`, or `describe`) within the file. - If the file is empty or doesn't contain any tests, you'll encounter the "No tests found" error. 6. Update Playwright: - Make sure you're using an up-to-date version of Playwright. - Run the following command to check your current version: ```sh npx @playwright/test --version ``` - If needed, update Playwright to the latest version: ```sh npm install @playwright/test@latest ``` 7. Install Browsers: - Ensure that you've installed the necessary browsers (Chromium, Firefox, or WebKit) for Playwright. - Run the following command to install browsers: ```sh npx playwright install ``` 8. Run the Test Again: - After making the necessary adjustments, try running your test again: ```sh npx playwright test ./tests/example.spec.js ``` Remember to adapt the commands above to match your specific file paths and test file names --
Hi Raghav! I tried to run a recorded test in debug mode but it got blocked. I quit the test and i got 'Testing stopped early after 1 maximum allowed failures. 1 failed [chromium] > record4_iPhone11_demo.spec.js:7:5 > test 2 did not run'. Could you please let me know what's the possible reason? I mention that when running without debug mode it works fine
When running your recorded test in debug mode, you encountered an issue where the test got blocked and stopped early. The error message you received indicates that there was a failure during the test execution. Let's explore some possible reasons for this behavior: 1. Breakpoints and Pausing: - Debug mode allows you to set breakpoints in your test code. When a breakpoint is hit, the test execution pauses, allowing you to inspect variables, step through code, and troubleshoot. - Check if you have any breakpoints set in your test file. If a breakpoint is causing the test to pause indefinitely, it could lead to the test being blocked. 2. Timeouts: - Debugging can sometimes cause tests to run slower due to additional processing and interactions with the debugging environment. - Ensure that your test has appropriate timeouts set. If a test step takes longer than the specified timeout, it may result in a failure. 3. Browser Profile: - By default, Playwright uses the Chromium profile for debugging. However, you can debug your tests on different browsers. - Verify that the browser profile you're using for debugging is configured correctly. You can switch profiles to see if the issue persists. 4. Strict Mode Violations: - Debugging may reveal strict mode violations or other issues that were not apparent during regular test execution. - Review your test code for any strict mode violations or other potential issues. 5. VS Code Extension: - If you're using Visual Studio Code (VS Code), consider using the Playwright extension for a better debugging experience. - The extension allows you to set breakpoints, step through tests, and see error messages directly in VS Code. 6. Live Debugging: - Take advantage of live debugging features in VS Code. You can interactively edit locators, pick elements, and see changes live in the browser window. - Ensure that you're using the correct locators for your test steps.
Muni Short Answer: No, Playwright does not support Internet Explorer (IE) browser applications out of the box Longer Explanation: Playwright is built on top of the browser's DevTools protocol, which is not available in Internet Explorer. IE uses a different automation API, called Internet Explorer Automation (IEA), which is not compatible with Playwright Workaround: If you need to automate IE, you can use other tools like Selenium WebDriver with the IE driver or Microsoft's own UI Automation API. However, these solutions have their own limitations and may not offer the same level of functionality as Playwright -
Hi sir .. Whatever u showed in video..same thing I followed.. Using this command npx playwright test it will run example.spec.js file .. While using specific file name like npx playwright test .\tests\example.spec.js It shows Error: no tests found ??
Hi Poornima When running Playwright tests using the command `npx playwright test`, you may encounter the "Error: no tests found" message if Playwright cannot locate any test files in the specified directory. This error typically occurs when there are no test files present or if the path to the test files is incorrect To resolve this issue, make sure to check the following: 1. Verify the test file path: Double-check the path you provided for the test file (`.\tests\example.spec.js`). Ensure that the path is correct and that the file exists in the specified location. It's important to provide the correct relative or absolute path to the test file 2. Check the file extension: Ensure that the test file has the `.spec.js` extension. Playwright looks for test files with this specific extension. If your test file has a different extension or if the file is not recognized as a test file, Playwright will not be able to find any tests 3. Confirm the correct working directory: Make sure you are running the command from the correct working directory. The path you provide should be relative to the current working directory. Check that you are in the right directory when executing the command 4. Verify the test file structure: Ensure that the test file follows the proper structure and contains valid tests. Each test file should have at least one test function defined using a test framework such as Jest or Mocha. Make sure your test file contains valid test cases that can be discovered by the test runner Once you have verified these aspects, try running the command again with the correct test file path. If the issue persists, consider checking for any additional error messages or logs that may provide further information about the problem It's also worth noting that Playwright supports various test frameworks, and you need to have the appropriate test runner and configuration set up to execute the tests correctly. Ensure that you have the necessary dependencies installed and the proper test framework configuration in place By following these steps and ensuring the correct file paths and test configurations, you should be able to run Playwright tests successfully using the specified file name
Hi Raghav, I am working in an organisation and doing just manual testing .. but now in my project need to work with playwright.. but still I have no idea for automation.. ( know some basic knowledge) can you please help me that how can I learn automation step by step.. what I need to learn first .. I have seen your video for playwright but still not understanding from where I need to start to learn automation.
If you need to work with Playwright, just start with it and learn whatever is needed along with Playwright. Basically you will be able to use playwright to automate basic web testing in a few days and then you can add to it as needed
I want to run the code only in chrome and edge, but since i have selected chrome, edge and firefox browsers while doing 'Test: Install playwright', all the 3 browsers are being used. How to unselect firefox now?
Swapna There are two ways to unselect Firefox in Playwright: 1. **Using the Playwright API:** ```js // Import the Playwright API. const { chromium, edge } = require('playwright'); // Create a new browser context using the Chromium browser. const browser = await chromium.launch({ headless: true }); // Create a new page in the browser context. const page = await browser.newPage(); // Unselect Firefox from the list of available browsers. await browser.use({ browsers: [chromium, edge] }); // Navigate to the desired URL. await page.goto('example.com'); // ... ``` 2. **Using the Playwright CLI:** ``` npx playwright test --browsers chromium edge ``` This will launch the test runner with only the Chromium and Edge browsers. To unselect Firefox permanently, you can edit the `PLAYWRIGHT_BROWSERS` environment variable. This variable specifies the browsers that Playwright will use by default. To unselect Firefox, set the `PLAYWRIGHT_BROWSERS` environment variable to a comma-separated list of the browsers that you want to use, excluding Firefox. For example, to unselect Firefox and use only Chromium and Edge, you would set the `PLAYWRIGHT_BROWSERS` environment variable to the following: ``` export PLAYWRIGHT_BROWSERS=chromium,edge ``` Once you have unselected Firefox, you can run your Playwright tests as usual and only the Chromium and Edge browsers will be used.
Hello I followed all steps but when I come to run test with "npx playwright tests" I got this ------> error: unknown command 'tests' . Can you please help me
Hi Raghav, I have query please that we can use C# language in writing code for automation in Playwright, but while installation we have selected JavaScript language. So, how can we change it to C# please or will it allow to run the tests when we write code in C# please?
Ashish Unfortunately, you cannot directly use C# for writing automation tests in Playwright when you've installed it with JavaScript language selected. Playwright is designed with specific language bindings for each supported language, and the installation process sets up the necessary files and configurations for the chosen language. However, there are a few options to address your situation: 1. Reinstall Playwright with C# support: The recommended approach is to reinstall Playwright with C# support enabled. Here's how: * Uninstall the current Playwright installation. * Use the following command to reinstall Playwright with C# support: ``` npm install --save-dev playwright @playwright/csharp ``` * This will install the necessary C# libraries and configure Playwright for C# development. 2. Use the Playwright Sharp library: While not officially supported by the Playwright team, the Playwright Sharp library allows you to write automation tests in C# for Chromium, WebKit, and Firefox. Here's what you need to do: * Install Playwright Sharp using NuGet: ``` Install-Package PlaywrightSharp ``` * Configure Playwright Sharp by referencing the appropriate libraries and setting up drivers. Refer to the Playwright Sharp documentation for detailed instructions: 3. Consider alternative tools: If C# is a strict requirement for your project, other automation testing tools like Selenium offer better support for C#. While Playwright offers some unique features, tools like Selenium may be a suitable alternative. Important Note: Regardless of the approach you choose, remember that writing tests in a language different from the installation language requires additional configuration and maintenance. Consider the long-term implications and maintenance overhead before choosing a solution. I hope this clarifies your options and helps you move forward with your automation project
Hi Sir, i am facing issue "Failed to install browsers" Error: Failed to download chromium Any suggestion on this please i am running using java My current organization is stopping the browsers to get downloaded from the playwright http url even though if we try downloading and place the files manually in ms-playwright folder those are getting overridden during launch/run
To resolve the issue of Playwright failing to download browsers due to organizational restrictions, here are some suggestions tailored to your situation: Fix for Browser Download Issue Skip Browser Downloads: Set the environment variable to stop automatic downloads: PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1 Manually Install Browsers: Download the required browser binaries from an external network. Place the binaries in a secure, accessible directory. Specify Browser Path in Code: Update your Playwright Java code to use the manually downloaded browser: Browser browser = playwright.chromium().launch(new BrowserType.LaunchOptions() .setExecutablePath("C:/path/to/chromium")); Alternative: Use Internal Server If possible, host the browser files on an internal server and set this variable: PLAYWRIGHT_DOWNLOAD_HOST=/playwright This prevents Playwright from trying to download from restricted URLs
Dear Sir i have faced below issue PS D:\playwright> npx playwright test .\tests\demo_orange.spec.js --project chromium --headed Error: No tests found. Make sure that arguments are regular expressions matching test files. You may need to escape symbols like "$" or "*" and quote the arguments
mir in the path of test file try using single forward slashes / e.g D:\playwright> npx playwright test ./tests/demo_orange.spec.js --project chromium --headed also make sure path is correct
Hi Prem To maximize the browser window during launch in Playwright, you can use the `--maximize` flag when launching the browser. Here's an example in JS: const { chromium } = require('playwright'); (async () => { const browser = await chromium.launch({ headless: false, args: ['--start-maximized'] }); const context = await browser.newContext(); const page = await context.newPage(); // Rest of your code... })(); In this example, the `--start-maximized` argument is passed to the browser's `launch` function, which will maximize the browser window when it is launched. Adjust the code according to the browser you are using (e.g., `chromium`, `firefox`, `webkit`). By setting `headless=False`, the browser window will be visible. If you want to run in headless mode, you can remove the `headless=False` argument. Remember to import the necessary modules and adjust the code based on your specific use case.

Neha Here are some quick steps to troubleshoot: Check Node.js Installation: Run node -v to see if it's installed. If not, install it from the Node.js website Verify npm Installation: Run npm -v. If it's missing, reinstall Node.js, which includes npm Check Playwright Installation: Run npx playwright --version. If not installed, use npm init playwright@latest Run as Administrator: On Windows, try running your terminal as Administrator -
Hi Raghav, i am following the same steps but i don't know when I am running npx playwright test to run the sample it says ERROR: no tests found. Even though i can see 'example.spec.js' under test folder. Could you please guide asap. Thanks
If you are encountering the error "Error: No tests found" when running `npx playwright test`, it typically means that Playwright was unable to locate any test files in the specified directory. Here are a few suggestions to resolve the issue: 1. Check the test file path: Double-check that the path you provided, `.\tests\test-1.js`, is correct and that the test file actually exists in that location. Make sure the file extension is `.js` for JavaScript test files. 2. Confirm the test file structure: Ensure that your test file follows the correct structure for Playwright tests. It should typically include imports for Playwright, test functions or test suites, and assertions. Here's a basic example: ```javascript const { chromium } = require('playwright'); (async () => { const browser = await chromium.launch(); const page = await browser.newPage(); // Your test code here await browser.close(); })(); ``` 3. Verify the test framework: Make sure you are using a supported test framework (e.g., Jest, Mocha, or Jasmine) to define and execute your tests. Playwright integrates with these frameworks to run tests. 4. Install necessary dependencies: Ensure that you have all the required dependencies installed. Run `npm install` to make sure you have the necessary packages specified in your `package.json` file. 5. Check Playwright version: Ensure that you have the latest version of Playwright installed. You can run `npm outdated playwright` to check for updates and `npm update playwright` to update to the latest version. By verifying these aspects, you should be able to resolve the "Error: No tests found" issue and successfully run your Playwright tests.
Rohini If you're encountering the "Cannot find module" error while using Playwright, there are a few steps you can take to resolve it: 1. Check Playwright Installation: - First, ensure that you have Playwright installed in your project. You can install it using npm: ``` npm install -D playwright ``` - Make sure it's listed in your `package.json` under the `"dependencies"` or `"devDependencies"` section. 2. Transpile TypeScript Manually (for @playwright/test): - If you're using TypeScript with `@playwright/test`, note that it doesn't consider your `tsconfig.json` when transpiling your TS files. Custom path mappings might not work as expected. - To transpile TypeScript manually, follow the instructions in the [Playwright documentation](playwright.dev/docs/test-typescript). - This workaround ensures that your custom path mappings are taken into account. 3. Check Your tsconfig.json: - Verify that your `tsconfig.json` is correctly configured. - Ensure that the paths for your custom modules (like `@common/common`) are correctly defined. - Make sure the TypeScript compiler options match your project setup. 4. Restart TypeScript Server (if needed): - Sometimes, IDEs might cache TypeScript information. Try restarting your IDE or the TypeScript server. - For Visual Studio Code, open the command palette (Mac: cmd+shift+p, Windows: ctrl+shift+p), type "restart ts," and select "TypeScript: Restart TS server." 5. Check Your Project Structure: - Confirm that your project structure aligns with your TypeScript configuration. - Verify that your test files are in the correct location (usually `cypress/integration` for Playwright tests). 6. Reinstall Playwright (if needed): - If you've tried everything else, consider reinstalling Playwright: ``` npx playwright install ``` ---
Hi Raghav I was getting an error for web kit like below..version 1.44.1 Running 6 tests using 6 workers 1) [webkit] › example.spec.js:4:1 › has title ──────────────────────────────────────────────────── Error: browserContext.newPage: Target page, context or browser has been closed 2) [webkit] › example.spec.js:11:1 › get started link ──────────────────────────────────────────── Error: browserContext.newPage: Target page, context or browser has been closed 2 failed [webkit] › example.spec.js:4:1 › has title ───────────────────────────────────────────────────── [webkit] › example.spec.js:11:1 › get started link ───────────────────────────────────────────── 4 passed (9.0s), out of 6 only 4 are passed
Ramya The error you're encountering with Playwright and WebKit-specifically, the "Error: browserContext.newPage: Target page, context, or browser has been closed"-can be tricky to troubleshoot. Let's explore some potential solutions: 1. Browser Context Lifecycle: - This error often occurs when a browser context or page is closed prematurely. Ensure that you're managing browser contexts correctly. - Make sure you're not closing a context or page before attempting to use it in subsequent steps. 2. Webkit-Specific Issues: - WebKit might have specific quirks or limitations. Consider checking the Playwright documentation for any known issues related to WebKit. - Update Playwright to the latest version. Sometimes, newer versions include fixes for specific browser-related problems. 3. Network Idle vs. DOMContentLoaded: - You mentioned using `networkIdle` for Chrome. Try using `domcontentloaded` instead for WebKit. - WebKit might behave differently during page navigation events. Adjust the wait strategy accordingly. 4. Headless Mode: - You mentioned running the tests in headless mode. Try running them without headless mode to see if the issue persists. - If the issue disappears, it might be related to headless mode in WebKit. 5. Debugging: - Add logging statements to your test steps. Print messages before and after each navigation action to see where the issue occurs. - Use `console.log` or similar methods to track the flow of your test. 6. Playwright Updates: - Ensure you're using the latest version of Playwright. Run `npm install -D @playwright/test@latest` to update. - Check the release notes for any browser-specific fixes. Remember that debugging browser automation can be challenging, but systematically narrowing down the issue will help you find a solution. Good luck --
Hi Sir, I tried to run the test using the following command npx playwright test .\tests\example.spec.js but it is saying no tests found. Please reply for this.
Hi Rajkumar, There could be several reasons why the tests are not being found by the npx playwright test command. Here are some possible solutions to try: Check the file path: Make sure that the file path to the test file is correct. Double-check that the file is located in the specified directory and that the file name is spelled correctly. Check the test file name: Make sure that the test file is named with a .spec.js extension. If the file extension is different, the test runner might not recognize the file as a test file. Check the test function name: Make sure that the test function in the test file is named with the prefix "test". For example, a test function should be named "testExample" rather than "example". Check the test runner configuration: Check the configuration file for the test runner to ensure that it is configured correctly. The configuration file is usually named playwright.config.js. Make sure that the file is located in the correct directory and that it specifies the correct test directory. Check the test runner version: Make sure that you have the latest version of the test runner. Run npx playwright test --version to check the version number, and then compare it with the latest version available on the official Playwright website. Check for syntax errors: Make sure there are no syntax errors in the test file or any of the imported modules. Syntax errors can cause the test runner to fail to recognize the test file. Hopefully, one of these solutions helps you resolve the issue
I am trying to find the best opensource automation tool to automate an application that the main functionality is in an html canvas. I need to select things from the canvas and drag and drop them. Coordinates are not preferred as they can change so looking for a tool that can locate an image within an image and then perform mouse operations. Any help is appreciated.
Sure, I can suggest a few tools that might be helpful for automating operations on an HTML canvas: 1. Cypress: Cypress is a powerful end-to-end testing framework that can interact with the DOM, making it a good choice for testing applications with an HTML canvas. There's also a plugin called `cypress-plugin-snapshots` that supports visual regression testing, which could be useful for your use case 2. Selenium: Selenium is another popular open-source automation tool that supports multiple browsers and operating systems. It allows you to write automated tests for web applications and has wide community support. 3. Telerik Test Studio: Although not open-source, Telerik Test Studio has added support for many of the HTML5 tags like Canvas, Audio, and Video tags. All the HTML tags are accessible using code and are under the `ArtOfTest.WebAii.HtmlControls` namespace. For the `HtmlCanvas`, you actually have access to the 2D Context of the control Remember, each tool has its own strengths and weaknesses, and the best tool often depends on your specific needs and context. It's a good idea to try out a few different tools to see which one works best for your application ---
hey man, can you help me? I wanted to run only one test so i said:npx playwright test .\tests\sometest.test.ts but i got the error message: Error: No tests found My Playwright folder is located on the desktop but everything else is the same as for you.
There could be several reasons why you are getting the "No tests found" error message when trying to run a single test using Playwright. Here are a few possible solutions you can try: Check the path of the test file you are trying to run: Ensure that the path to the test file you want to run is correct. In your case, the test file is located in the "tests" folder. Make sure that the path to the folder is correct. Check the name of the test file: Ensure that the name of the test file you want to run is correct. Double-check that the file name is spelled correctly, including the file extension. Check the name of the test function: Ensure that the name of the test function you want to run is correct. Double-check that the name of the function is spelled correctly, including any capitalization or punctuation. Ensure the test is exported: Make sure that the test function is exported from the test file. You should have something like export test('My Test', async () => {...}); Ensure you have installed the required dependencies: Make sure that you have installed all the necessary dependencies for your project, including Playwright, Jest or Mocha, and any other required packages. You can do this by checking the dependencies section of your package.json file. Try running all tests: If none of the above solutions work, try running all tests in your project to see if any tests are found. You can do this by running npx playwright test without specifying a test file. Check the configuration file: Ensure that the configuration file is set up correctly. In your case, the configuration file should be playwright.config.ts and should include a reference to the folder containing your test files, like this: module.exports = { testMatch: ["**/tests/*.test.ts"], }; By following these steps, you should be able to identify and resolve the issue preventing your test from running.
Hi Bhagyalakshmi Here are the commands you can use to run tests one by one in browsers using Playwright: * **To run a single test file:** ``` npx playwright test ``` For example, to run the `landing-page.spec.ts` file, you would use the following command: ``` npx playwright test landing-page.spec.ts ``` * **To run a set of test files:** ``` npx playwright test ... ``` For example, to run the `landing-page.spec.ts` and `login-page.spec.ts` files, you would use the following command: ``` npx playwright test landing-page.spec.ts login-page.spec.ts ``` * **To run tests that match a specific pattern:** ``` npx playwright test -g ``` For example, to run all tests that have the word "login" in the file name, you would use the following command: ``` npx playwright test -g login ``` * **To run tests in a specific browser:** ``` npx playwright test --browser ``` For example, to run the `landing-page.spec.ts` file in Chrome, you would use the following command: ``` npx playwright test landing-page.spec.ts --browser chrome ``` * **To run tests in all browsers:** ``` npx playwright test --browsers all ``` This will run all tests in Chrome, Firefox, and Edge. * **To run tests in headless mode:** ``` npx playwright test --headed false ``` This will run the tests in headless mode, which means that the browsers will not open a visible window. * **To run tests in debug mode:** ``` npx playwright test --debug ``` This will run the tests in debug mode, which allows you to step through the tests line by line. I hope this helps

Hi Ragav, I can see 4 workers in my pc but in the report i could see only 3 browsers "chromium,firefox and webkit". Could you please let me know why there is difference in number? Running 6 tests using 4 workers 6 passed (21.9s)
Hi Bhagyalakshmi here is why you might see a difference in the number of workers and browsers in Playwright: *You are running different tests on different browsers:* If you are running different tests on different browsers, each test will be run in a separate worker. For example, if you are running 6 tests, each using a different browser, you will see 6 workers and 6 browsers in the report *You are using different browser versions:* If you are using different browser versions, each version will be run in a separate worker. For example, if you are running 6 tests, each using a different version of Chrome, you will see 6 workers and 6 browsers in the report *You are using different browser profiles:* If you are using different browser profiles, each profile will be run in a separate worker. For example, if you are running 6 tests, each using a different profile of Chrome, you will see 6 workers and 6 browsers in the report In your case, it sounds like you are running 6 tests, each using a different browser. This would explain why you see 4 workers and 3 browsers in the report. Here are some additional things to keep in mind: *The number of workers and browsers may not match exactly:* The number of workers and browsers may not match exactly, depending on the specific tests that you are running. For example, if you are running a test that requires two browsers, it will be run in a single worker *The number of workers and browsers may change over time:* The number of workers and browsers may change over time, depending on the resources that are available on your machine. For example, if you are running a lot of tests at the same time, Playwright may create more workers and browsers to handle the load. I hope this helps
I am getting error while executing npx playwright test one spec .js [Error - could not determine executable to run and no tests found . how to resolve this
The error message you're encountering, "could not determine executable to run and no tests found," typically indicates that Playwright was unable to locate any test files to execute. This can happen for a few reasons: 1. Incorrect File Path: Ensure that the file path to your test file is correct. If you're in the same directory as the test file, you can try running it with a relative path like `./one.spec.js`. Try using forward slashes / in your path 2. File Naming Convention: Playwright expects test files to follow a specific naming convention, usually `*.spec.js` or `*.test.js`. Make sure your test file's name matches these patterns. 3. Configuration Issue: Check your Playwright configuration file (if you have one) to ensure it's not misconfigured in a way that would exclude your test file from being recognized. 4. Version Mismatch: There might be a version mismatch issue if you have multiple versions of Playwright installed. Ensure that you're using the correct version of Playwright that corresponds with your test files. 5. Syntax Error: A syntax error in the test file can sometimes cause this issue. Verify that your test file is free of syntax errors and is properly structured. 6. Grep Pattern: If you're using command line arguments or configuration settings to set a filter on tests to run, make sure that the grep pattern isn't excluding all of your tests. Here's a command you can try to execute your test file: ```shell npx playwright test one.spec.js ``` If you're still facing issues, you might want to check the documentation for Playwright or seek help from the community forums where you can share more details about your setup and the exact commands you're using. Remember to replace `one.spec.js` with the actual name of your test file.
Hi Gavrav, when i run this command "npx playwright test .\tests\example.spec.js" says "no tests found", but when i ran 'npx playwright test' it executed. Could you please help me ?
Hi Prashanthi, The error message "no tests found" is indicating that the Playwright test runner cannot find any test files to run. This error is likely occurring because the test runner is not able to locate the test file specified in the command npx playwright test .\tests\example.spec.js. Here are a few things to check: File path: Verify that the file path specified in the command .\tests\example.spec.js is correct and that the file exists in the specified location. Make sure the path is relative to the current directory and not an absolute path. File extension: Verify that the file has the correct extension, in this case '.spec.js', which is commonly used for Playwright test files. Test syntax: Verify that the test file contains valid JavaScript code and that the tests are written in a format that Playwright can understand. If you continue to experience this issue, it may be helpful to check the Playwright documentation for more information or to seek assistance from the Playwright community.
Hi Raghav, i am not able to go in my folder by command can you help me with this 'npx Playwright test .\tests\example.spec.js example.spec.js' getting no tests found error. And also if i don't give no of worker still getting 6 workers sometime 3 workers
Hi Kusumdevi, To navigate to the folder containing your Playwright tests, you can use the cd command in your terminal. For example, if your tests are located in a folder named tests, you can navigate to that folder by running the following command: cd tests Once you are in the tests folder, you can run your Playwright tests using the following command: npx playwright test example.spec.js To navigate to the folder containing your Playwright tests, you can use the cd command in your terminal. For example, if your tests are located in a folder named tests, you can navigate to that folder by running the following command: bash Copy code cd tests Once you are in the tests folder, you can run your Playwright tests using the following command: bash Copy code npx playwright test example.spec.js This assumes that your example.spec.js file is located in the tests folder. Regarding the number of workers, Playwright by default uses the number of logical cores on your CPU to determine the number of workers to use for parallel test execution. If you want to override this default behavior and set the number of workers explicitly, you can use the --workers option. For example, to set the number of workers to 3, you can use the following command: npx playwright test --workers=3 example.spec.js If you do not specify the --workers option, Playwright will use the default behavior of determining the number of workers based on your CPU's logical cores.
Hi, If I have a second folder with another test script in it, what would be the command to run that specific test only. i.e. tests > example.spec.js test-demo > demo.spec js What would be the command to run the demo.spec.js only. I have tried npx playwright test demo.spec.js it showed "Error: No tests found".
Abdullah To run the specific test script `demo.spec.js` located in the `test-demo` folder, use the following command: ```bash npx playwright test test-demo/demo.spec.js ``` Give single forward slash / in the path of the test file and after typing few characters press 'tab' to auto-complete (this is to ensure you do not make any typing errors)
Hi I have a doubt that if I need to run a playwright script that is present in another folder not in same folder which the test folder of playwright script is present is that possible to run that script which command do I need to use
You can run a Playwright script from a different folder using the npx command. Here's an example: Let's say your script is located in a folder called scripts and your test folder is located in a folder called tests. The directory structure would look like this: project/ scripts/ script.js tests/ test.js ... To run the script.js from the tests folder, you can use the following command: npx playwright run scripts/script.js This will execute the script.js script located in the scripts folder. If you want to run the script from a specific folder, you can use the --cwd option to specify the working directory. For example: npx playwright run --cwd ../scripts script.js This will run the script.js script from the scripts folder, but with the working directory set to the scripts folder. Note that you can also use the --config option to specify a custom configuration file. For example: npx playwright run --config ../scripts/playwright.config.js script.js This will use the playwright.config.js file located in the scripts folder as the configuration file for the script -
When I run example.spec.js using 'npx playwright test' command from VS Code terminal only one test passed. firefox and webkit tests fail. Is it a configuration issue?
When we run the test script "npx playwright test --project=chromium" it Running on 2 test using 2 workers . What actually it mean ? It should run only on one browser specfic ? Can you please clarify it ?
Jaiasree When you run `npx playwright test --project=chromium`, the command tells Playwright to execute your tests using the Chromium browser. Playwright uses workers to parallelize test execution for efficiency. In the message you received, Running on 2 tests using 2 workers means: 2 Tests: There are 2 test files/suites to be executed in your project. 2 Workers: Playwright has launched 2 separate worker processes to run these tests in parallel. This improves execution speed by running both tests concurrently on your machine. It will not necessarily run only on one browser. By default, Playwright runs tests in parallel across all browsers specified in your project configuration. So, if you don't have any specific browser configured, it will use all available browsers (usually Chromium, Firefox, and WebKit). To run tests only on a specific browser: 1. Use the `--browser` flag: ``` npx playwright test --project=chromium --browser=chromium ``` This will execute tests only in Chromium. You can replace `chromium` with `firefox` or `webkit` for other browsers. 2. Configure the project: You can set the default browser in your `playwright.config.js` or `playwright.config.ts` file: ```javascript module.exports = { projects: [ { name: 'chromium', use: { browser: 'chromium', }, }, ], }; ``` This configures the `chromium` project to use only the Chromium browser by default. Remember that running tests in parallel can benefit from multiple cores or threads on your machine. If you have limited resources, consider adjusting the number of workers with the `--workers` flag: ``` npx playwright test --project=chromium --browser=chromium --workers=1 ``` This will run tests in Chromium with only 1 worker, effectively simulating single-browser execution. I hope this clarifies how Playwright handles test execution and options for running tests in specific browsers
Thank you i found the issue, and now i have another problem I launched my test to log in to my app. After filling in the login boxes, it stops at the login screen@@RaghavPal it keeps waiting until the time runs out.
There are a few possible reasons why your Playwright test might be stopping at the login screen and waiting until the time runs out: * The login form is not submitting correctly. * The login form is submitting, but the response from the server is taking too long to arrive. * The login form is submitting correctly, but Playwright is not waiting for the login to complete before moving on to the next step in the test. To resolve this issue, you can try the following: * Check the console for any errors that might be preventing the login form from submitting correctly. * Use the `page.waitForNavigation()` method to wait for the page to navigate to the next page after the login form is submitted. * Use the `page.waitForLoadState()` method to wait for the page to load completely after the login form is submitted. Here is an example of how to use the `page.waitForNavigation()` method to wait for the page to navigate to the next page after the login form is submitted: ```typescript import { test, expect } from '@playwright/test'; test('should log in to the app', async ({ page }) => { await page.goto('example.com/login'); // Fill in the login form. await page.locator('button[type="submit"]').click(); // Wait for the page to navigate to the next page. await page.waitForNavigation(); // Verify that the user is logged in. await expect(page.locator('h1')).toContainText('Welcome, user!'); }); ``` Here is an example of how to use the `page.waitForLoadState()` method to wait for the page to load completely after the login form is submitted: ```typescript import { test, expect } from '@playwright/test'; test('should log in to the app', async ({ page }) => { await page.goto('example.com/login'); // Fill in the login form. await page.locator('button[type="submit"]').click(); // Wait for the page to load completely. await page.waitForLoadState('domcontentloaded'); // Verify that the user is logged in. await expect(page.locator('h1')).toContainText('Welcome, user!'); }); ```
Hello Raghav..how to execute the test only in one browser ? i mean you have shown option npx playwright test--project=chrominum ..but can it be controlled in the playwright.config.js file ? for ex : i wanted to use npx playwright test - but only executed in one browser
Hi Harish, yes, you can set in config file module.exports = { browser: 'chromium' // The browser you want to use for your test } For multiple browsers module.exports = { browser: ['chromium', 'firefox', 'webkit'] // The browser you want to use for your test }
@@RaghavPal Hello raghav..unfortunately i am not sure how to edit the config file ... in the playwright docs offical page ... const config = { use: { baseURL: 'localhost:3000', browserName: 'firefox', headless: true, }, }; ---------------- but seems to be different from the default config.js file content
What is the difference between cmd using debug with line number and cmd with specifying the test & debugging. I saw no difference . if no difference what is the use?
Savitha In Playwright, when it comes to debugging tests, there are two primary methods using the command line: 1. Using `debug` with Line Number: - Syntax: `npx playwright test --debug /:` - Purpose: Sets a breakpoint directly on the specified line number within a test file, pausing execution upon reaching that point. - Advantages: - Granular control over test execution, allowing you to inspect variables, step through code line by line, and examine the page state at a specific point. - Useful for isolating complex issues within a single test. - Disadvantages: - Requires knowing the exact line number where the problem occurs, which might not always be easy to pinpoint. - Can be time-consuming for debugging multiple issues or when the exact line is unclear. 2. Specifying the Test & Debugging: - Syntax: `npx playwright test --debug --grep ""` - Purpose: Runs the entire test suite or a group of tests matching the provided regular expression, launching the Playwright Inspector for debugging. - Advantages: - More efficient for debugging multiple tests or broader issues affecting parts of the test suite. - Provides an interactive UI for examining page elements, inspecting network requests, and experimenting with changes on the fly. - Disadvantages: - Less precise than direct line-number breakpoints, requiring some exploration within the Inspector to diagnose problems. - Debugging all tests can be slow for large test suites. Choosing the Right Approach: - For pinpoint debugging or isolated issues: Use `debug` with line number. - For broader debugging or issues affecting multiple tests: Specify the test & debug. Additional Considerations: - Browser Selection: Use `--browser ` (e.g., `--browser chromium`) to target specific browsers. - Headless/Headed Mode: Control browser visibility with `--headed` or `--headless`. - Configuration Overrides: Modify Playwright settings using command-line arguments or a configuration file. Example: Suppose you suspect an issue on line 25 of `test_login.spec.ts` within the `login` test: ```bash npx playwright test --debug login/test_login.spec.ts:25 ``` This sets a breakpoint on line 25, allowing you to step through the test execution and investigate the problem in detail. ..
@@RaghavPal Thanks for the information, I kind of understood , but given the line number for the debug , it has to be the start of test right ? (where we use test as the keyword). I might be wrong , please clarify
Savitha Here are the different ways to debug tests and their purposes: 1. Debugging Tests with Line Numbers: - When you run a test using the command line with a specific line number, Playwright opens the inspector at that exact line in your test file. - Purpose: - Allows you to set breakpoints directly in your test code. - You can step through the test line by line, inspect variables, and analyze the flow. - Useful for pinpointing issues within a specific test case. - Command: ``` npx playwright test your-test-file.spec.ts:line-number --debug ``` 2. Debugging Tests with Test Name: - When you specify the test name (instead of a line number), Playwright runs that specific test and opens the inspector. - Purpose: - Focuses on a particular test scenario. - Useful for debugging a specific test without navigating through the entire test file. - Command: ``` npx playwright test your-test-file.spec.ts --test "Your Test Name" --debug ``` 3. Playwright Inspector: - The Playwright Inspector is a GUI tool that provides a visual interface for debugging. - Purpose: - Allows you to step through your tests, live edit locators, pick locators, and see actionability logs. - Provides a more interactive debugging experience. - Command: ``` npx playwright test your-test-file.spec.ts --debug ``` - The `--debug` flag opens the inspector. 4. VS Code Extension for Debugging: - For an even better developer experience, use the VS Code extension for debugging. - Purpose: - Debug your tests directly in VS Code. - Set breakpoints, step through tests, and see error messages. - Live edit locators and pick locators. - Benefits: - Error messages are shown in the editor. - You can interactively debug your tests. - Easily switch between different browsers for debugging. - Use the Playwright Inspector within VS Code.
Hi, not aware if there is some in-built feature in playwright, but you can always do this using command line, Can create a batch file having the run commands and can schedule it to run using windows scheduler or any other way Another option will be to use a CI CD tool like Jenkins
Aastha Absolutely! Integrating TestRail with Playwright using the TestRail CLI is straightforward. Here's how you can do it: *1. Install TestRail CLI:* *Prerequisite:* Ensure you have Python 3.10 or higher installed on your system. *Option 1 (Recommended):* Use pip to install the TestRail CLI: ``` pip install trcli ``` *Option 2 (Alternative):* Download the appropriate wheel file for your operating system from the TestRail CLI releases page ([github.com/gurock/trcli](github.com/gurock/trcli)) and install it manually: ``` python3 -m pip install /path/to/trcli--py3-.whl ``` *2. Configure TestRail CLI:* * Run `trcli config init` to set up your TestRail configuration. * Enter your TestRail base URL, username, and password when prompted. * Optionally, provide a project ID and save the configuration file for future use. *3. Integrate TestRail with Playwright:* * Import the `trcli` package in your Playwright test script: ```python from trcli import Client # Replace these values with your details client = Client(base_url="YOUR_TESTRAIL_BASE_URL", username="YOUR_USERNAME", password="YOUR_PASSWORD") ``` * Use the `trcli` client to interact with TestRail throughout your tests: *Create test runs:* ```python client.runs.create(project_id=1, name="My Playwright Test Run") ``` *Add test results:* ```python # For passed tests client.results.add(run_id=run_id, case_id=1, status=1) # For failed tests client.results.add(run_id=run_id, case_id=1, status=5, comment="Test failed due to...") ``` *Get test details:* ```python test_case = client.tests.get(project_id=1, case_id=1) print(f"Test Case Title: {test_case['title']}") ```
Hi Raghav, Playwright inspector is not opening when i run the test in debug mode, I am using plawright-1.35.1, do i need to install any extension for it ?
Hi Abhilash The Playwright inspector should open automatically when you run your tests in debug mode. If it is not opening, there are a few things you can check: * Make sure that you are using the latest version of Playwright. * Make sure that you have the `PWDEBUG` environment variable set to `1`. * Make sure that you are not running your tests in headless mode. If you have checked all of these things and the Playwright inspector is still not opening, you may need to install the Playwright DevTools extension. This extension is available for Chrome, Firefox, and Edge. To install the Playwright DevTools extension, follow these steps: * Open the Chrome Web Store. * Search for "Playwright DevTools". * Click on the "Add to Chrome" button. * Click on the "Add extension" button. Once the Playwright DevTools extension is installed, you should be able to open the Playwright inspector by pressing `Ctrl`+`Shift`+`I`. If you are still having trouble opening the Playwright inspector, you can try the following: * Restart your computer. * Uninstall and reinstall Playwright. * File an issue on the Playwright GitHub repository. I hope this helps

Hi Raghav. Thanks for your lessons. I currently facing one issue in testing block I can not see any test to execute through play button. Instead it’s showing no tests have been found in this workspace yet can please help me on this
Shiva
Check your command, in the path of the test file try giving single forward slashes
File Naming: Ensure test files are named with .spec.ts, .spec.js, .test.ts, or .test.js suffixes (e.g., example.spec.js).
Test Structure: Verify that your test files are structured correctly. A basic example:
const { test, expect } = require('@playwright/test');
test('basic test', async ({ page }) => {
await page.goto('example.com');
expect(await page.title()).toBe('Example Domain');
});
Playwright Installation: Ensure Playwright is installed:
npm install @playwright/test
Configuration File: Check for a playwright.config.js or playwright.config.ts file in the root of your project.
Run from CLI: Execute tests directly via the command line:
npx playwright test
IDE Settings: If using an IDE, ensure its Playwright extension is properly configured.
Restart IDE: Sometimes a simple restart can resolve detection issues.
Update Dependencies: Ensure all dependencies are up to date:
npm update @playwright/test

Hello Raghav. I need to say that you're very good teacher. Very clear and simple to understand. I have one question ... why, when I run any tests from Terminal, using (for example) command: npx playwright test .\tests\example.spec.js ... I got message : Error: No tests found ... ?
Hi,
If you are running tests in Playwright using the command npx playwright test, you need to make sure that your tests are organized in a certain way so that Playwright can discover and run them.
By default, Playwright looks for test files in a directory named tests, and for test files that have a name ending in .spec.js or .test.js. So if your test file is named example.spec.js, make sure it is located in a folder named tests in the root of your project directory.
If your test file is located in a different directory or has a different name, you can specify the file or directory using the --test-match option when running the npx playwright test command.
For example, if your test file is located in a directory named my-tests and has a name ending in .test.js, you can run the test using the following command:
npx playwright test --test-match="./my-tests/**/*.test.js"
Make sure to specify the correct path to your test file or directory.
If you are still getting the error "No tests found", make sure that your test file contains at least one test case that is defined using the test function from a test runner such as Jest or Mocha. For example:
const { test, expect } = require('@playwright/test');
test('example test', async ({ page }) => {
await page.goto('example.com');
expect(await page.title()).toBe('Example Domain');
});
This test case uses the test function from the @playwright/test package to define a test named "example test". Make sure that your test file contains at least one test case defined in this way.
try: npx playwright test example.spec.js (Just skip the '.\tests\' part and it should work)

Hi Ragav! Thank you for posting detailed videos.They are very helpful for anyone starting to learn Playwright with no background. I want to know why some tests fail in "webkit" or "firefox" browser libraries but pass with just chromium.However the error shows that page timed out, in the terminal we see the reason is "the webpage has been blocked by our organization".If that's the case we shouldn't be able to run the testcase in chromium as well, right?
Anushka
Here are potential reasons for the inconsistencies you're experiencing with Playwright tests across different browsers, along with troubleshooting steps:
1. Browser-Specific Rendering or Behavior:
Websites might render or behave differently in different browsers due to varying JavaScript engines, CSS implementations, or browser extensions.
Inspect the website's behavior in each browser manually to identify discrepancies.
Adapt your tests to handle browser-specific variations using conditional logic or Playwright's browser-specific selectors and actions.
2. Browser Configuration or Settings:
Check for inconsistencies in browser configurations like privacy settings, content blocking, or proxy settings.
Ensure consistent configurations across browsers using Playwright's browser launch options.
3. Playwright Version or Browser Compatibility:
Update to the latest Playwright version for compatibility fixes.
Consult Playwright's documentation for known compatibility issues between specific browser versions and Playwright.
4. Network Issues or Firewall Rules:
Investigate network restrictions or firewall rules that might selectively block certain browsers or websites.
Review organization-wide policies and collaborate with IT if necessary.
5. Timing Issues:
Adjust timeout settings for page loads or actions to accommodate potential differences in loading times across browsers.
Use explicit waits for specific elements or conditions to ensure tests proceed only when the page is ready.
6. Debugging and Troubleshooting:
Enable verbose logging or debugging in Playwright to gather more information about browser interactions.
Isolate the problematic tests to narrow down the root cause.
Test in different environments to rule out environment-specific issues.
Specific to the "webpage blocked" error:
Double-check organization policies and firewall rules to understand the exact restrictions.
Check if Chromium has any exceptions or bypasses for these restrictions.
Consider using a VPN or proxy to temporarily bypass restrictions for testing purposes if allowed within your organization.
Thankyou so much..!! Its very very amazing. I wish I had seen this video before!!! Amazing.

Hi Raghav, thanks a lot for wonderful content, i am getting below error, seems command is correct and folder is also present :
PS C:\Playwright_Test> npx playwright test .\tests\example.spec.js
Error: No tests found.
Make sure that arguments are regular expressions matching test files.
You may need to escape symbols like "$" or "*" and quote the arguments.
Chandan
There are other comments with the same issue... pls check if any of those solutions work for you.. else you can check this:
1. Check Test File Path:
- Ensure that the path to your test file (`example.spec.js`) is correct.
- Verify that the file exists in the specified location (`.\tests\example.spec.js`).
2. Regular Expressions and Special Characters:
- The error message suggests that you might need to escape special characters like "$" or "*".
- Make sure your test file path doesn't contain any special characters that need escaping.
3. Quoting Arguments:
- If your test file path contains spaces or other special characters, consider enclosing it in double quotes:
```
npx playwright test ".\tests\example.spec.js"
```
4. Check File Content:
- Ensure that your `example.spec.js` file contains valid test cases.
- Verify that the test cases are correctly defined using Playwright's syntax.
5. Update Playwright:
- Make sure you're using the latest version of Playwright. Update it if necessary:
```
npx playwright update
```
6. Run with Absolute Path:
- Try running the test with an absolute path instead of a relative path:
```
npx playwright test C:\Playwright_Test\tests\example.spec.js
```
7. Check Test Naming Convention:
- Ensure that your test functions follow the correct naming convention (e.g., `test('should do something', async () => {...})`).
8. Check Test Configuration:
- Verify that your test configuration (e.g., `jest.config.js` or `playwright.config.js`) points to the correct test files.
9. Debugging Logs:
- If the issue persists, check the debug logs for more details:
```
npx playwright test --debug .\tests\example.spec.js
```
10. Reinstall Playwright:
- If none of the above steps work, consider reinstalling Playwright:
```
npm uninstall -g playwright
npm install -g playwright
```
Remember to adapt these steps based on your specific setup and requirements.

Hi Raghav, i cant see the details from code in the test report. This cannot be opened any further. I only see the main fields with the text and steps. Is there another way to show us how to make a POM and especially in combination with the recording function?
Ahmed
When using Playwright for testing, you can explore test reports in a few ways:
1. HTML Reporter:
- After your test completes, an HTML report is generated. It shows a full breakdown of your tests, including browsers used, test durations, and individual steps.
- You can filter the report by browsers, passed tests, failed tests, skipped tests, and flaky tests.
- Clicking on each test allows you to explore errors and view each step of the test
2. Command Line Report:
- You can see a concise report directly in the terminal using the `list` reporter. It prints a line for each test being run.
- To enable step rendering, you can pass the `printSteps: true` configuration option¹.
- Example usage:
```bash
npx playwright test --reporter=list
```
3. Browser Window Report (Debbie Codes):
- Run the following command to open a browser window with a detailed report of your tests:
```bash
npx playwright show-report
```
- This report includes information about browsers used, test durations, and individual steps
Remember that Playwright's built-in reporters provide different levels of detail, so choose the one that best suits your needs. If you're interested in creating a Page Object Model (POM) in combination with the recording function

Hi raghav, do you have a video in which you explain how to implement cucumber with playwright? Thank you
Not yet, will work on it
I am using visual studio code and trying to learn playwright using C#. I want to run the code in HEADED mode and used command set HEADED=1 dotnet test but it is not running. Could you please help in this.
Ankita
The command `set HEADED=1` is used to set an environment variable `HEADED` to `1`. This is correct.
However, the `dotnet test` command is used to run unit tests in.NET, but it doesn't directly relate to Playwright or Headed mode.
Check the Playwright configuration
To run Playwright tests in Headed mode, you need to configure Playwright to use Headed mode. You can do this by setting the `headless` option to `false` in your Playwright configuration.
In C#, you can do this by creating a `PlaywrightOptions` instance and setting the `Headless` property to `false`:
```csharp
using Microsoft.Playwright;
// Create a new instance of PlaywrightOptions
var options = new PlaywrightOptions
{
Headless = false
};
// Launch the browser with the options
using var playwright = await Playwright.CreateAsync(options);
```
Run the tests
Once you've configured Playwright to use Headed mode, you can run your tests as usual using the `dotnet test` command.
Verify the environment variable
Although you've set the `HEADED` environment variable, it's not necessary to set it explicitly. The `Headless` property in the `PlaywrightOptions` instance should be enough to run the tests in Headed mode.
However, if you still want to use the environment variable, make sure it's set correctly before running the tests. You can do this by running the command `set HEADED=1` in your terminal or command prompt before running the `dotnet test` command.
To summarize, you need to configure Playwright to use Headed mode by setting the `Headless` property to `false` in your Playwright configuration. Then, you can run your tests using the `dotnet test` command

Hi Raghav, could you please let me know what is End-to-End testing testing for a user story and how can we write an E2E tests as a manual tester?
Ashish
End-to-End (E2E) testing is a comprehensive approach that evaluates the entire software system by simulating real-world user scenarios from start to finish. Here's what you need to know:
1. What is E2E Testing?
- E2E testing ensures that the application works as expected from the end user's perspective
- It covers the entire workflow, including the user interface, backend services, databases, and network communication
- The goal is to validate overall behavior, functionality, reliability, performance, and security.
2. Writing E2E Tests as a Manual Tester:
- Identify test scenarios: Understand the user stories and identify the critical scenarios.
- Map the steps in each scenario: Break down the user flow into specific steps.
- Perform manual testing: Execute the steps manually to verify functionality.
- Automate the tests: Once you've validated the manual steps, consider automating them using testing tools or frameworks.
- Add your tests to the continuous integration (CI) pipeline for regular execution
Remember, E2E testing helps ensure that your application behaves correctly across different layers and interfaces, providing a seamless experience for users

@@RaghavPal Thank you so much for such a detailed explanation.
Thanks a lot on guiding on how to write and perform E2E testing as a manual and automation tester, this really helps me a lot in understanding E2E testing in a broader way.
This is awesome thank you so much!
You're so welcome!
Which one best for java or JavaScript to use playwright
Venkatesh
Both are good, its the users choice and project requirements that you will have to go with
@Raghav for me npx playwright test .\tests\example.spec. doesn't work. It shows an error "Error: No tests found.
Make sure that arguments are regular expressions matching test files.
You may need to escape symbols like "$" or "*" and quote the arguments."
Clive
Please try by adding a single forward slash / in the path of file in your command, e.g.:
npx playwright test tests/example.spec.js
Here are a few things you can check to resolve the "No tests found" error:
1. File Naming: Ensure your test file has the correct suffix, such as `.spec.js` or `.test.js`. Playwright looks for these specific suffixes to identify test files⁴.
2. File Path: Double-check the file path you're providing. It should be relative to the root of your project. For example, if your test file is located in the `tests` folder, the command should be:
```bash
npx playwright test tests/example.spec.js
```
3. Escaping Symbols: If your file path contains special characters like `$` or `*`, make sure to escape them or quote the entire path. For example:
```bash
npx playwright test "tests/example.spec.js"
```
4. Configuration File: Verify that your `playwright.config.js` or `playwright.config.ts` file is correctly set up and points to the directory containing your tests. The `testDir` property should be set to the folder where your test files are located
5. Empty Test Files: Ensure that your test files are not empty and contain valid test cases. Playwright will throw an error if it doesn't find any test cases in the specified files

Hi Raghav, how do we implement data driven testing with playwright? Read and write from excel or csv ?
Hi Debayudh,
You can implement data-driven testing in Playwright by reading test data from external files like Excel or CSV, and then passing that data into your test scripts.
Here's an example of how you can read data from a CSV file and use it in your Playwright test scripts:
Install the csv-parser npm package using the following command:
npm install csv-parser
Create a CSV file containing your test data, with each row representing a separate set of test data. For example:
username,password
testuser1,pass123
testuser2,pass456
testuser3,pass789
Create a Playwright test script that reads the data from the CSV file, and then iterates through each row to run the test with each set of data. Here's an example of what the test script could look like:
const playwright = require('playwright');
const csv = require('csv-parser');
const fs = require('fs');
// Read the CSV file containing test data
const testData = [];
fs.createReadStream('testdata.csv')
.pipe(csv())
.on('data', (row) => {
testData.push(row);
})
.on('end', () => {
// Iterate through each row of test data and run the test
for (const data of testData) {
describe(`Test with data: ${JSON.stringify(data)}`, () => {
let browser;
let context;
let page;
beforeAll(async () => {
// Launch the browser and create a new context and page
browser = await playwright.chromium.launch();
context = await browser.newContext();
page = await context.newPage();
});
afterAll(async () => {
// Close the browser when the test is finished
await browser.close();
});
test('Test Login', async () => {
// Use the test data to fill in the login form
await page.goto('example.com/login');
await page.fill('#username', data.username);
await page.fill('#password', data.password);
await page.click('#submit');
// Assert that the login was successful
await page.waitForSelector('#welcome-message');
const welcomeMessage = await page.textContent('#welcome-message');
expect(welcomeMessage).toBe(`Welcome, ${data.username}!`);
});
});
}
});
This test script reads the test data from the CSV file using the csv-parser package, and then iterates through each row of test data to run the test with that data. In this example, the test script logs in to a website using the username and password from the test data, and then asserts that the login was successful.
You can modify this example to read test data from other types of external files, such as Excel or JSON, by using the appropriate libraries or packages to parse those file formats.
Hello sir I'm a new suscriber I was trying to run a test on my Work tools however I may need to authenticate my Okta account otherwise the test will fail since it will not proceeded to the actual webpage, Is there any easy way to implement OKTA authentication to my tests, thanks and cheers
Hi Cherry,
Yes, you can use the auth option of Playwright's Page.goto() method to authenticate with Okta. Here's an example:
const { chromium } = require('playwright');
const expectWebauthn = require('expect-webauthn');
(async () => {
const browser = await chromium.launch();
const context = await browser.newContext();
// Go to the Okta login page
const page = await context.newPage();
await page.goto('example.okta.com/');
// Click the login button to trigger Okta authentication
await page.click('#login-button');
// Wait for the WebAuthn/FIDO2 authentication flow to appear
await expectWebauthn(page).toDisplay({ timeout: 30000 });
// Perform the authentication flow using a test credential
await expectWebauthn(page).toAutoSubmit({
timeout: 30000,
credential: {
id: 'test-credential-id',
rawId: 'dGVzdC1jcmVkZW50aWFsLWlk',
response: {
authenticatorData: 'test-authenticator-data',
clientDataJSON: 'test-client-data-json',
signature: 'test-signature',
userHandle: 'test-user-handle',
},
type: 'public-key',
},
});
// Okta authentication should now be successful and you can proceed to test the actual webpage
await page.goto('example.okta.com/my-account');
// ...
})();
This example assumes that you have already registered a test credential in your Okta account and have its id, rawId, response, and type values. If you don't have these values, you can create a test credential using the webauthn-test-data library.
Note that this is just a basic example and you may need to modify it based on your specific authentication flow and webpage.

Great.. keep going
Hi Raghav, does playwright has built in libraries for Dynamics 365 application, given that both are from Microsoft
Playwright doesn't have built-in libraries for Dynamics 365 .. but you can automate it using Playwright's general web automation features
Dynamics 365 uses dynamic IDs, s, and custom UI components, which require careful handling with robust selectors (aria-label, data-*, etc.) and Playwright's support (frameLocator)
For authentication, you can automate login flows or reuse tokens via Playwright's storageState.
Example for logging in:
javascript
Copy code
const { chromium } = require('playwright');
(async () => {
const browser = await chromium.launch({ headless: false });
const page = await browser.newPage();
await page.goto('your-dynamics365-url');
await page.fill('input[type="email"]', 'your-email@example.com');
await page.click('button:has-text("Next")');
await page.fill('input[type="password"]', 'your-password');
await page.click('button:has-text("Sign in")');
await page.waitForSelector('#dashboard-selector');
// Interact with Dynamics UI here
await browser.close();
})();
Playwright works well for Dynamics 365 with proper scripting but may require extra effort for complex scenarios
-
No, Playwright does not have built-in libraries specifically for Dynamics 365. However, it can be used to automate Dynamics 365 applications by interacting with the web elements like any other web application. You'll need to write custom scripts to handle Dynamics 365's specific features and complexities.
Error: Project(s) "Microsoft" not found. Available named projects: "chromium", "Microsoft Edge", "firefox", "webkit" - Error while running the test on edge. added the name: 'Microsoft Edge',
use: { ...devices['Desktop Edge'], channel: 'msedge' },
},
in the config file. What is causing this error
Sridhar
The error message "Error: Project(s) 'Microsoft' not found. Available named projects: 'chromium', 'Microsoft Edge', 'firefox', 'webkit'" indicates that Playwright is unable to find the project named "Microsoft" when you're running your tests on Edge. This error occurs despite having the following configuration in your file:
```
name: 'Microsoft Edge',
use: { ...devices['Desktop Edge'], channel: 'msedge' },
```
This suggests that there might be a mismatch between the project name used in your test script and the one defined in your configuration file.
Here are some potential causes and solutions for this error:
*1. Inconsistent Project Names:*
* Ensure the project name used in your test script and the configuration file matches exactly.
* Verify if you're accidentally using "Microsoft" instead of "Microsoft Edge" anywhere in your code.
* Double-check the spelling and case sensitivity of the project names.
*2. Outdated Playwright Version:*
* Make sure you're using the latest version of Playwright. Older versions might have different project names or require specific configurations.
* Update your Playwright version to ensure compatibility and bug fixes.
*3. Incorrect Configuration Syntax:*
* Double-check the syntax of your configuration file, especially around the project name and `use` properties.
* Refer to the Playwright documentation for the correct syntax for configuring projects.
*4. Missing Browser Binaries:*
* Playwright might not have downloaded the necessary browser binaries for Microsoft Edge.
* Run `playwright install --with-edge` to download the required browser binaries.
*5. Playwright Bugs:*
* In rare cases, there might be bugs in Playwright affecting project recognition or configuration.
* Check the Playwright bug tracker for any reported issues related to Edge project configuration.
* If you suspect a bug, consider reporting it to the Playwright team with a detailed description and test case.
*Here are some additional tips:*
* Share your test script and the complete configuration file for further analysis.
* Provide the version of Playwright you're using for specific troubleshooting steps.
* Consult the Playwright documentation and community forums for assistance with your specific use case.
By systematically analyzing the error message, exploring the potential causes, and implementing the suggested solutions, you should be able to resolve the "Error: Project(s) 'Microsoft' not found" issue and successfully run your Playwright tests on Edge.
Hi Raghav, my test cases failed with firefox and webkit, just passed with chromium. Can you tell me the problem? Thank you.
Ben
It's not uncommon to encounter differences in test behavior across different browsers when using Playwright. Let's explore some potential reasons for the discrepancies you're observing:
1. Browser-Specific Issues:
- Firefox: Playwright tests may fail in Firefox due to various reasons. Some common issues include:
- Network Logs: Network logs might not work out of the box for `playwright-firefox`. You can try specifying `ignoreHTTPSErrors: true` while creating a new context to enable network logs
- Missing Dependencies: Ensure that all dependencies are installed. You can check the [Playwright CLI documentation](playwright.dev/docs/cli) for details on required dependencies
- Webkit: You mentioned that Webkit fails with errors like "Element out of the ViewPort." This could be due to differences in rendering or viewport handling between Webkit and other browsers.
2. Flakiness and Race Conditions:
- Flakiness in test results can occur due to race conditions, timing issues, or asynchronous behavior. Here are some things to consider:
- Await Statements: Ensure that you're using `await` correctly in your test code. Missing `await` can lead to unpredictable behavior.
- Dependencies: Double-check that all asynchronous operations (e.g., network requests, element interactions) are properly awaited.
- Parallel Execution: When running multiple tests with multiple workers, there might be race conditions. Consider using proper synchronization mechanisms (e.g., `Promise.all`, `waitFor`, etc.).
3. Debugging Techniques:
- To diagnose the issue further:
- Set the `DEBUG=pw:api` environment variable to see detailed logs when Playwright interacts with the page
- Inspect the failing test cases and look for patterns or commonalities in the failures.
- Consider isolating specific test cases to narrow down the problem.
4. Storage State Reuse:
- You mentioned reusing the storage state from login to complete other tests. Ensure that the state is correctly maintained across tests.
- Verify that the login state is consistent and not causing unexpected side effects.
5. Viewport and Element Visibility:
- For the "Element out of the ViewPort" issue, check if the viewport size differs between browsers. Adjust the viewport size if needed.
- Verify that elements are consistently visible and interactable across browsers.
Remember that cross-browser testing is essential to ensure robust test coverage
Hi @Raghav. You should have put video 4 in the position of 3 and swap them. You need to show how to write test before you run them.
Hi Prabal, I added this first as we get a prebuilt set of tests on installing Playwright and it will be good to run something and see
@@RaghavPal Just gave my feedback as someone learning from your videos. It made more sense watching 4 then 3.

Hi Raghav, Also May I know in which file I can see the execution time of steps?
Sure, you can see the execution time of steps in the Playwright test report. The test report is a file that is generated after you run your tests. It contains information about each test, including the execution time of each step.
To view the execution time of steps in the Playwright test report, you can use the following command:
```
npx playwright test --report playwright-report.html
```
This will generate a file called `playwright-report.html` in the current directory. You can open this file in a web browser to view the test report.
The execution time of each step is shown in the "Steps" section of the test report. The time is shown in milliseconds
sir i got an error when i run the command "npx playwright test .\tests\example.spec.js"
the error is "Error: No tests found"
but when i run "npx playwright test"
the commands runs successfully
Hi Saad
The error "Error: No tests found" means that the Playwright test runner cannot find any tests to run. This can happen for a number of reasons, including:
* The test file does not exist. Make sure that the test file exists and that it is in the current directory.
* The test file is not a valid Playwright test file. Make sure that the test file is a valid Playwright test file. A valid Playwright test file must have the .spec.js extension and it must contain a function that is annotated with the @test() decorator.
* The test file is not included in the test suite. Make sure that the test file is included in the test suite. The test suite is a list of files that are to be run by the Playwright test runner. You can specify the test suite by using the --suite option.
Here are some steps on how to fix the error "Error: No tests found" in Playwright:
1. Make sure that the test file exists.
2. Make sure that the test file is a valid Playwright test file.
3. Make sure that the test file is included in the test suite.
If you have followed all of these steps and you are still getting the error "Error: No tests found", you can try searching for help online. There are a number of forums and websites that can help you troubleshoot this issue
Here are some additional tips for running Playwright tests:
* Use the --suite option to specify the test suite. This will allow you to run a specific test suite from the command line.
* Use the --watch option to run the test suite continuously. This will allow you to see the results of the tests as they are run.
* Use the --headless option to run the tests in headless mode. This will allow you to run the tests without a graphical user interface.
I hope this helps

The error message you're encountering, "No tests found," is a common issue when running Playwright tests. It typically occurs due to configuration or path-related problems. Let's troubleshoot this together! Here are some steps you can take to resolve it:
1. Check Your Test File Path:
- Ensure that the path to your test file (`example.spec.js`) is correct.
- Double-check that the file exists in the specified location (`.\tests\example.spec.js`).
- Make sure there are no typos or missing directories in the path.
2. Use Correct File Paths:
- When specifying the test file path, use forward slashes (`/`) instead of backslashes (`\`) to separate directories.
- Example:
```sh
npx playwright test ./tests/example.spec.js
```
3. Quotes and Special Characters:
- If your test file path contains spaces or special characters, enclose it in double quotes.
- Example:
```sh
npx playwright test "./tests/my test file.spec.js"
```
4. Escape Symbols:
- If your test file path contains symbols like `$` or `*`, escape them using a backslash (`\`).
- Example:
```sh
npx playwright test "./tests/my\$test\*file.spec.js"
```
5. Check Test File Content:
- Ensure that your `example.spec.js` file contains valid test cases.
- Verify that you have defined test functions (e.g., `it`, `test`, or `describe`) within the file.
- If the file is empty or doesn't contain any tests, you'll encounter the "No tests found" error.
6. Update Playwright:
- Make sure you're using an up-to-date version of Playwright.
- Run the following command to check your current version:
```sh
npx @playwright/test --version
```
- If needed, update Playwright to the latest version:
```sh
npm install @playwright/test@latest
```
7. Install Browsers:
- Ensure that you've installed the necessary browsers (Chromium, Firefox, or WebKit) for Playwright.
- Run the following command to install browsers:
```sh
npx playwright install
```
8. Run the Test Again:
- After making the necessary adjustments, try running your test again:
```sh
npx playwright test ./tests/example.spec.js
```
Remember to adapt the commands above to match your specific file paths and test file names

Hi Raghav! I tried to run a recorded test in debug mode but it got blocked. I quit the test and i got 'Testing stopped early after 1 maximum allowed failures. 1 failed [chromium] > record4_iPhone11_demo.spec.js:7:5 > test 2 did not run'. Could you please let me know what's the possible reason? I mention that when running without debug mode it works fine
When running your recorded test in debug mode, you encountered an issue where the test got blocked and stopped early. The error message you received indicates that there was a failure during the test execution. Let's explore some possible reasons for this behavior:
1. Breakpoints and Pausing:
- Debug mode allows you to set breakpoints in your test code. When a breakpoint is hit, the test execution pauses, allowing you to inspect variables, step through code, and troubleshoot.
- Check if you have any breakpoints set in your test file. If a breakpoint is causing the test to pause indefinitely, it could lead to the test being blocked.
2. Timeouts:
- Debugging can sometimes cause tests to run slower due to additional processing and interactions with the debugging environment.
- Ensure that your test has appropriate timeouts set. If a test step takes longer than the specified timeout, it may result in a failure.
3. Browser Profile:
- By default, Playwright uses the Chromium profile for debugging. However, you can debug your tests on different browsers.
- Verify that the browser profile you're using for debugging is configured correctly. You can switch profiles to see if the issue persists.
4. Strict Mode Violations:
- Debugging may reveal strict mode violations or other issues that were not apparent during regular test execution.
- Review your test code for any strict mode violations or other potential issues.
5. VS Code Extension:
- If you're using Visual Studio Code (VS Code), consider using the Playwright extension for a better debugging experience.
- The extension allows you to set breakpoints, step through tests, and see error messages directly in VS Code.
6. Live Debugging:
- Take advantage of live debugging features in VS Code. You can interactively edit locators, pick elements, and see changes live in the browser window.
- Ensure that you're using the correct locators for your test steps.
Hi Raghav, I have query related to browser.
Whether playwright able to handle IE browser applications. Please confirm.
Muni
Short Answer: No, Playwright does not support Internet Explorer (IE) browser applications out of the box
Longer Explanation: Playwright is built on top of the browser's DevTools protocol, which is not available in Internet Explorer. IE uses a different automation API, called Internet Explorer Automation (IEA), which is not compatible with Playwright
Workaround: If you need to automate IE, you can use other tools like Selenium WebDriver with the IE driver or Microsoft's own UI Automation API. However, these solutions have their own limitations and may not offer the same level of functionality as Playwright

Hi sir ..
Whatever u showed in video..same thing I followed..
Using this command npx playwright test it will run example.spec.js file ..
While using specific file name like npx playwright test .\tests\example.spec.js
It shows Error: no tests found ??
Hi Poornima
When running Playwright tests using the command `npx playwright test`, you may encounter the "Error: no tests found" message if Playwright cannot locate any test files in the specified directory. This error typically occurs when there are no test files present or if the path to the test files is incorrect
To resolve this issue, make sure to check the following:
1. Verify the test file path: Double-check the path you provided for the test file (`.\tests\example.spec.js`). Ensure that the path is correct and that the file exists in the specified location. It's important to provide the correct relative or absolute path to the test file
2. Check the file extension: Ensure that the test file has the `.spec.js` extension. Playwright looks for test files with this specific extension. If your test file has a different extension or if the file is not recognized as a test file, Playwright will not be able to find any tests
3. Confirm the correct working directory: Make sure you are running the command from the correct working directory. The path you provide should be relative to the current working directory. Check that you are in the right directory when executing the command
4. Verify the test file structure: Ensure that the test file follows the proper structure and contains valid tests. Each test file should have at least one test function defined using a test framework such as Jest or Mocha. Make sure your test file contains valid test cases that can be discovered by the test runner
Once you have verified these aspects, try running the command again with the correct test file path. If the issue persists, consider checking for any additional error messages or logs that may provide further information about the problem
It's also worth noting that Playwright supports various test frameworks, and you need to have the appropriate test runner and configuration set up to execute the tests correctly. Ensure that you have the necessary dependencies installed and the proper test framework configuration in place
By following these steps and ensuring the correct file paths and test configurations, you should be able to run Playwright tests successfully using the specified file name

I want to run the code only in chrome and edge, but since i have selected chrome, edge and firefox browsers while doing 'Test: Install playwright', all the 3 browsers are being used. How to unselect firefox now?
Swapna
There are two ways to unselect Firefox in Playwright:
1. **Using the Playwright API:**
```js
// Import the Playwright API.
const { chromium, edge } = require('playwright');
// Create a new browser context using the Chromium browser.
const browser = await chromium.launch({ headless: true });
// Create a new page in the browser context.
const page = await browser.newPage();
// Unselect Firefox from the list of available browsers.
await browser.use({ browsers: [chromium, edge] });
// Navigate to the desired URL.
await page.goto('example.com');
// ...
```
2. **Using the Playwright CLI:**
```
npx playwright test --browsers chromium edge
```
This will launch the test runner with only the Chromium and Edge browsers.
To unselect Firefox permanently, you can edit the `PLAYWRIGHT_BROWSERS` environment variable. This variable specifies the browsers that Playwright will use by default. To unselect Firefox, set the `PLAYWRIGHT_BROWSERS` environment variable to a comma-separated list of the browsers that you want to use, excluding Firefox.
For example, to unselect Firefox and use only Chromium and Edge, you would set the `PLAYWRIGHT_BROWSERS` environment variable to the following:
```
export PLAYWRIGHT_BROWSERS=chromium,edge
```
Once you have unselected Firefox, you can run your Playwright tests as usual and only the Chromium and Edge browsers will be used.

Hi Raghav, I have query please that we can use C# language in writing code for automation in Playwright, but while installation we have selected JavaScript language. So, how can we change it to C# please or will it allow to run the tests when we write code in C# please?
Ashish
Unfortunately, you cannot directly use C# for writing automation tests in Playwright when you've installed it with JavaScript language selected. Playwright is designed with specific language bindings for each supported language, and the installation process sets up the necessary files and configurations for the chosen language.
However, there are a few options to address your situation:
1. Reinstall Playwright with C# support:
The recommended approach is to reinstall Playwright with C# support enabled. Here's how:
* Uninstall the current Playwright installation.
* Use the following command to reinstall Playwright with C# support:
```
npm install --save-dev playwright @playwright/csharp
```
* This will install the necessary C# libraries and configure Playwright for C# development.
2. Use the Playwright Sharp library:
While not officially supported by the Playwright team, the Playwright Sharp library allows you to write automation tests in C# for Chromium, WebKit, and Firefox. Here's what you need to do:
* Install Playwright Sharp using NuGet:
```
Install-Package PlaywrightSharp
```
* Configure Playwright Sharp by referencing the appropriate libraries and setting up drivers. Refer to the Playwright Sharp documentation for detailed instructions:
3. Consider alternative tools:
If C# is a strict requirement for your project, other automation testing tools like Selenium offer better support for C#. While Playwright offers some unique features, tools like Selenium may be a suitable alternative.
Important Note:
Regardless of the approach you choose, remember that writing tests in a language different from the installation language requires additional configuration and maintenance. Consider the long-term implications and maintenance overhead before choosing a solution.
I hope this clarifies your options and helps you move forward with your automation project

Hi Sir,
i am facing issue "Failed to install browsers"
Error: Failed to download chromium
Any suggestion on this please i am running using java
My current organization is stopping the browsers to get downloaded from the playwright http url
even though if we try downloading and place the files manually in ms-playwright folder those are getting overridden during launch/run
To resolve the issue of Playwright failing to download browsers due to organizational restrictions, here are some suggestions tailored to your situation:
Fix for Browser Download Issue
Skip Browser Downloads:
Set the environment variable to stop automatic downloads:
PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1
Manually Install Browsers:
Download the required browser binaries from an external network.
Place the binaries in a secure, accessible directory.
Specify Browser Path in Code:
Update your Playwright Java code to use the manually downloaded browser:
Browser browser = playwright.chromium().launch(new BrowserType.LaunchOptions()
.setExecutablePath("C:/path/to/chromium"));
Alternative: Use Internal Server
If possible, host the browser files on an internal server and set this variable:
PLAYWRIGHT_DOWNLOAD_HOST=/playwright
This prevents Playwright from trying to download from restricted URLs
Dear Sir i have faced below issue PS D:\playwright> npx playwright test .\tests\demo_orange.spec.js --project chromium --headed
Error: No tests found.
Make sure that arguments are regular expressions matching test files.
You may need to escape symbols like "$" or "*" and quote the arguments
mir
in the path of test file try using single forward slashes /
e.g
D:\playwright> npx playwright test ./tests/demo_orange.spec.js --project chromium --headed
also make sure path is correct

Hi Raghav,
How to maximize browser during launch in playwright ??
Hi Prem
To maximize the browser window during launch in Playwright, you can use the `--maximize` flag when launching the browser. Here's an example in JS:
const { chromium } = require('playwright');
(async () => {
const browser = await chromium.launch({ headless: false, args: ['--start-maximized'] });
const context = await browser.newContext();
const page = await context.newPage();
// Rest of your code...
})();
In this example, the `--start-maximized` argument is passed to the browser's `launch` function, which will maximize the browser window when it is launched. Adjust the code according to the browser you are using (e.g., `chromium`, `firefox`, `webkit`).
By setting `headless=False`, the browser window will be visible. If you want to run in headless mode, you can remove the `headless=False` argument.
Remember to import the necessary modules and adjust the code based on your specific use case.

If you are encountering the error "Error: No tests found" when running `npx playwright test`, it typically means that Playwright was unable to locate any test files in the specified directory.
Here are a few suggestions to resolve the issue:
1. Check the test file path: Double-check that the path you provided, `.\tests\test-1.js`, is correct and that the test file actually exists in that location. Make sure the file extension is `.js` for JavaScript test files.
2. Confirm the test file structure: Ensure that your test file follows the correct structure for Playwright tests. It should typically include imports for Playwright, test functions or test suites, and assertions. Here's a basic example:
```javascript
const { chromium } = require('playwright');
(async () => {
const browser = await chromium.launch();
const page = await browser.newPage();
// Your test code here
await browser.close();
})();
```
3. Verify the test framework: Make sure you are using a supported test framework (e.g., Jest, Mocha, or Jasmine) to define and execute your tests. Playwright integrates with these frameworks to run tests.
4. Install necessary dependencies: Ensure that you have all the required dependencies installed. Run `npm install` to make sure you have the necessary packages specified in your `package.json` file.
5. Check Playwright version: Ensure that you have the latest version of Playwright installed. You can run `npm outdated playwright` to check for updates and `npm update playwright` to update to the latest version.
By verifying these aspects, you should be able to resolve the "Error: No tests found" issue and successfully run your Playwright tests.
Hi Raghav Sir, I am getting "Cannot find node module", How to resolve this?
Rohini
If you're encountering the "Cannot find module" error while using Playwright, there are a few steps you can take to resolve it:
1. Check Playwright Installation:
- First, ensure that you have Playwright installed in your project. You can install it using npm:
```
npm install -D playwright
```
- Make sure it's listed in your `package.json` under the `"dependencies"` or `"devDependencies"` section.
2. Transpile TypeScript Manually (for @playwright/test):
- If you're using TypeScript with `@playwright/test`, note that it doesn't consider your `tsconfig.json` when transpiling your TS files. Custom path mappings might not work as expected.
- To transpile TypeScript manually, follow the instructions in the [Playwright documentation](playwright.dev/docs/test-typescript).
- This workaround ensures that your custom path mappings are taken into account.
3. Check Your tsconfig.json:
- Verify that your `tsconfig.json` is correctly configured.
- Ensure that the paths for your custom modules (like `@common/common`) are correctly defined.
- Make sure the TypeScript compiler options match your project setup.
4. Restart TypeScript Server (if needed):
- Sometimes, IDEs might cache TypeScript information. Try restarting your IDE or the TypeScript server.
- For Visual Studio Code, open the command palette (Mac: cmd+shift+p, Windows: ctrl+shift+p), type "restart ts," and select "TypeScript: Restart TS server."
5. Check Your Project Structure:
- Confirm that your project structure aligns with your TypeScript configuration.
- Verify that your test files are in the correct location (usually `cypress/integration` for Playwright tests).
6. Reinstall Playwright (if needed):
- If you've tried everything else, consider reinstalling Playwright:
```
npx playwright install
```

Ramya
The error you're encountering with Playwright and WebKit-specifically, the "Error: browserContext.newPage: Target page, context, or browser has been closed"-can be tricky to troubleshoot. Let's explore some potential solutions:
1. Browser Context Lifecycle:
- This error often occurs when a browser context or page is closed prematurely. Ensure that you're managing browser contexts correctly.
- Make sure you're not closing a context or page before attempting to use it in subsequent steps.
2. Webkit-Specific Issues:
- WebKit might have specific quirks or limitations. Consider checking the Playwright documentation for any known issues related to WebKit.
- Update Playwright to the latest version. Sometimes, newer versions include fixes for specific browser-related problems.
3. Network Idle vs. DOMContentLoaded:
- You mentioned using `networkIdle` for Chrome. Try using `domcontentloaded` instead for WebKit.
- WebKit might behave differently during page navigation events. Adjust the wait strategy accordingly.
4. Headless Mode:
- You mentioned running the tests in headless mode. Try running them without headless mode to see if the issue persists.
- If the issue disappears, it might be related to headless mode in WebKit.
5. Debugging:
- Add logging statements to your test steps. Print messages before and after each navigation action to see where the issue occurs.
- Use `console.log` or similar methods to track the flow of your test.
6. Playwright Updates:
- Ensure you're using the latest version of Playwright. Run `npm install -D @playwright/test@latest` to update.
- Check the release notes for any browser-specific fixes.
Remember that debugging browser automation can be challenging, but systematically narrowing down the issue will help you find a solution.
Good luck

Hi Sir,
I tried to run the test using the following command
npx playwright test .\tests\example.spec.js
but it is saying no tests found.
Please reply for this.
Hi Rajkumar,
There could be several reasons why the tests are not being found by the npx playwright test command. Here are some possible solutions to try:
Check the file path:
Make sure that the file path to the test file is correct. Double-check that the file is located in the specified directory and that the file name is spelled correctly.
Check the test file name:
Make sure that the test file is named with a .spec.js extension. If the file extension is different, the test runner might not recognize the file as a test file.
Check the test function name:
Make sure that the test function in the test file is named with the prefix "test". For example, a test function should be named "testExample" rather than "example".
Check the test runner configuration:
Check the configuration file for the test runner to ensure that it is configured correctly. The configuration file is usually named playwright.config.js. Make sure that the file is located in the correct directory and that it specifies the correct test directory.
Check the test runner version:
Make sure that you have the latest version of the test runner. Run npx playwright test --version to check the version number, and then compare it with the latest version available on the official Playwright website.
Check for syntax errors:
Make sure there are no syntax errors in the test file or any of the imported modules. Syntax errors can cause the test runner to fail to recognize the test file.
Hopefully, one of these solutions helps you resolve the issue
I am trying to find the best opensource automation tool to automate an application that the main functionality is in an html canvas. I need to select things from the canvas and drag and drop them. Coordinates are not preferred as they can change so looking for a tool that can locate an image within an image and then perform mouse operations. Any help is appreciated.
Sure, I can suggest a few tools that might be helpful for automating operations on an HTML canvas:
1. Cypress: Cypress is a powerful end-to-end testing framework that can interact with the DOM, making it a good choice for testing applications with an HTML canvas. There's also a plugin called `cypress-plugin-snapshots` that supports visual regression testing, which could be useful for your use case
2. Selenium: Selenium is another popular open-source automation tool that supports multiple browsers and operating systems. It allows you to write automated tests for web applications and has wide community support.
3. Telerik Test Studio: Although not open-source, Telerik Test Studio has added support for many of the HTML5 tags like Canvas, Audio, and Video tags. All the HTML tags are accessible using code and are under the `ArtOfTest.WebAii.HtmlControls` namespace. For the `HtmlCanvas`, you actually have access to the 2D Context of the control
Remember, each tool has its own strengths and weaknesses, and the best tool often depends on your specific needs and context. It's a good idea to try out a few different tools to see which one works best for your application

My Playwright folder is located on the desktop but everything else is the same as for you.
There could be several reasons why you are getting the "No tests found" error message when trying to run a single test using Playwright.
Here are a few possible solutions you can try:
Check the path of the test file you are trying to run: Ensure that the path to the test file you want to run is correct. In your case, the test file is located in the "tests" folder. Make sure that the path to the folder is correct.
Check the name of the test file: Ensure that the name of the test file you want to run is correct. Double-check that the file name is spelled correctly, including the file extension.
Check the name of the test function: Ensure that the name of the test function you want to run is correct. Double-check that the name of the function is spelled correctly, including any capitalization or punctuation.
Ensure the test is exported: Make sure that the test function is exported from the test file. You should have something like export test('My Test', async () => {...});
Ensure you have installed the required dependencies: Make sure that you have installed all the necessary dependencies for your project, including Playwright, Jest or Mocha, and any other required packages. You can do this by checking the dependencies section of your package.json file.
Try running all tests: If none of the above solutions work, try running all tests in your project to see if any tests are found. You can do this by running npx playwright test without specifying a test file.
Check the configuration file: Ensure that the configuration file is set up correctly. In your case, the configuration file should be playwright.config.ts and should include a reference to the folder containing your test files, like this:
module.exports = {
testMatch: ["**/tests/*.test.ts"],
};
By following these steps, you should be able to identify and resolve the issue preventing your test from running.
Hi Raghav, May I know command used to run the tests one by one in the browsers?
Hi Bhagyalakshmi
Here are the commands you can use to run tests one by one in browsers using Playwright:
* **To run a single test file:**
```
npx playwright test
```
For example, to run the `landing-page.spec.ts` file, you would use the following command:
```
npx playwright test landing-page.spec.ts
```
* **To run a set of test files:**
```
npx playwright test ...
```
For example, to run the `landing-page.spec.ts` and `login-page.spec.ts` files, you would use the following command:
```
npx playwright test landing-page.spec.ts login-page.spec.ts
```
* **To run tests that match a specific pattern:**
```
npx playwright test -g
```
For example, to run all tests that have the word "login" in the file name, you would use the following command:
```
npx playwright test -g login
```
* **To run tests in a specific browser:**
```
npx playwright test --browser
```
For example, to run the `landing-page.spec.ts` file in Chrome, you would use the following command:
```
npx playwright test landing-page.spec.ts --browser chrome
```
* **To run tests in all browsers:**
```
npx playwright test --browsers all
```
This will run all tests in Chrome, Firefox, and Edge.
* **To run tests in headless mode:**
```
npx playwright test --headed false
```
This will run the tests in headless mode, which means that the browsers will not open a visible window.
* **To run tests in debug mode:**
```
npx playwright test --debug
```
This will run the tests in debug mode, which allows you to step through the tests line by line.
I hope this helps

Hi Ragav,
I can see 4 workers in my pc but in the report i could see only 3 browsers "chromium,firefox and webkit". Could you please let me know why there is difference in number?
Running 6 tests using 4 workers
6 passed (21.9s)
Hi Bhagyalakshmi
here is why you might see a difference in the number of workers and browsers in Playwright:
*You are running different tests on different browsers:* If you are running different tests on different browsers, each test will be run in a separate worker. For example, if you are running 6 tests, each using a different browser, you will see 6 workers and 6 browsers in the report
*You are using different browser versions:* If you are using different browser versions, each version will be run in a separate worker. For example, if you are running 6 tests, each using a different version of Chrome, you will see 6 workers and 6 browsers in the report
*You are using different browser profiles:* If you are using different browser profiles, each profile will be run in a separate worker. For example, if you are running 6 tests, each using a different profile of Chrome, you will see 6 workers and 6 browsers in the report
In your case, it sounds like you are running 6 tests, each using a different browser. This would explain why you see 4 workers and 3 browsers in the report.
Here are some additional things to keep in mind:
*The number of workers and browsers may not match exactly:* The number of workers and browsers may not match exactly, depending on the specific tests that you are running. For example, if you are running a test that requires two browsers, it will be run in a single worker
*The number of workers and browsers may change over time:* The number of workers and browsers may change over time, depending on the resources that are available on your machine. For example, if you are running a lot of tests at the same time, Playwright may create more workers and browsers to handle the load.
I hope this helps
I am getting error while executing npx playwright test one spec .js [Error - could not determine executable to run and no tests found . how to resolve this
The error message you're encountering, "could not determine executable to run and no tests found," typically indicates that Playwright was unable to locate any test files to execute. This can happen for a few reasons:
1. Incorrect File Path: Ensure that the file path to your test file is correct. If you're in the same directory as the test file, you can try running it with a relative path like `./one.spec.js`. Try using forward slashes / in your path
2. File Naming Convention: Playwright expects test files to follow a specific naming convention, usually `*.spec.js` or `*.test.js`. Make sure your test file's name matches these patterns.
3. Configuration Issue: Check your Playwright configuration file (if you have one) to ensure it's not misconfigured in a way that would exclude your test file from being recognized.
4. Version Mismatch: There might be a version mismatch issue if you have multiple versions of Playwright installed. Ensure that you're using the correct version of Playwright that corresponds with your test files.
5. Syntax Error: A syntax error in the test file can sometimes cause this issue. Verify that your test file is free of syntax errors and is properly structured.
6. Grep Pattern: If you're using command line arguments or configuration settings to set a filter on tests to run, make sure that the grep pattern isn't excluding all of your tests.
Here's a command you can try to execute your test file:
```shell
npx playwright test one.spec.js
```
If you're still facing issues, you might want to check the documentation for Playwright or seek help from the community forums where you can share more details about your setup and the exact commands you're using. Remember to replace `one.spec.js` with the actual name of your test file.
Thanks for the quick reply will check and get back to you! 🙂
Hi Gavrav, when i run this command "npx playwright test .\tests\example.spec.js" says "no tests found", but when i ran 'npx playwright test' it executed. Could you please help me ?
Hi Prashanthi,
The error message "no tests found" is indicating that the Playwright test runner cannot find any test files to run. This error is likely occurring because the test runner is not able to locate the test file specified in the command npx playwright test .\tests\example.spec.js.
Here are a few things to check:
File path: Verify that the file path specified in the command .\tests\example.spec.js is correct and that the file exists in the specified location. Make sure the path is relative to the current directory and not an absolute path.
File extension: Verify that the file has the correct extension, in this case '.spec.js', which is commonly used for Playwright test files.
Test syntax: Verify that the test file contains valid JavaScript code and that the tests are written in a format that Playwright can understand.
If you continue to experience this issue, it may be helpful to check the Playwright documentation for more information or to seek assistance from the Playwright community.

Hi Kusumdevi,
To navigate to the folder containing your Playwright tests, you can use the cd command in your terminal. For example, if your tests are located in a folder named tests, you can navigate to that folder by running the following command:
cd tests
Once you are in the tests folder, you can run your Playwright tests using the following command:
npx playwright test example.spec.js
To navigate to the folder containing your Playwright tests, you can use the cd command in your terminal. For example, if your tests are located in a folder named tests, you can navigate to that folder by running the following command:
bash
Copy code
cd tests
Once you are in the tests folder, you can run your Playwright tests using the following command:
bash
Copy code
npx playwright test example.spec.js
This assumes that your example.spec.js file is located in the tests folder.
Regarding the number of workers, Playwright by default uses the number of logical cores on your CPU to determine the number of workers to use for parallel test execution. If you want to override this default behavior and set the number of workers explicitly, you can use the --workers option. For example, to set the number of workers to 3, you can use the following command:
npx playwright test --workers=3 example.spec.js
If you do not specify the --workers option, Playwright will use the default behavior of determining the number of workers based on your CPU's logical cores.
Hi,
If I have a second folder with another test script in it, what would be the command to run that specific test only. i.e.

What would be the command to run the demo.spec.js only. I have tried npx playwright test demo.spec.js it showed "Error: No tests found".
Abdullah
To run the specific test script `demo.spec.js` located in the `test-demo` folder, use the following command:
```bash
npx playwright test test-demo/demo.spec.js
```
Give single forward slash / in the path of the test file and after typing few characters press 'tab' to auto-complete (this is to ensure you do not make any typing errors)
@@RaghavPal Thanks you it worked.
Hi I have a doubt that if I need to run a playwright script that is present in another folder not in same folder which the test folder of playwright script is present is that possible to run that script which command do I need to use
You can run a Playwright script from a different folder using the npx command. Here's an example:
Let's say your script is located in a folder called scripts and your test folder is located in a folder called tests. The directory structure would look like this:
project/
scripts/
script.js
tests/
test.js
...
To run the script.js from the tests folder, you can use the following command:
npx playwright run scripts/script.js
This will execute the script.js script located in the scripts folder.
If you want to run the script from a specific folder, you can use the --cwd option to specify the working directory. For example:
npx playwright run --cwd ../scripts script.js
This will run the script.js script from the scripts folder, but with the working directory set to the scripts folder.
Note that you can also use the --config option to specify a custom configuration file. For example:
npx playwright run --config ../scripts/playwright.config.js script.js
This will use the playwright.config.js file located in the scripts folder as the configuration file for the script

When we run the test script "npx playwright test --project=chromium" it Running on 2 test using 2 workers . What actually it mean ? It should run only on one browser specfic ? Can you please clarify it ?
Jaiasree
When you run `npx playwright test --project=chromium`, the command tells Playwright to execute your tests using the Chromium browser. Playwright uses workers to parallelize test execution for efficiency. In the message you received, Running on 2 tests using 2 workers means:
2 Tests: There are 2 test files/suites to be executed in your project.
2 Workers: Playwright has launched 2 separate worker processes to run these tests in parallel. This improves execution speed by running both tests concurrently on your machine.
It will not necessarily run only on one browser. By default, Playwright runs tests in parallel across all browsers specified in your project configuration. So, if you don't have any specific browser configured, it will use all available browsers (usually Chromium, Firefox, and WebKit).
To run tests only on a specific browser:
1. Use the `--browser` flag:
```
npx playwright test --project=chromium --browser=chromium
```
This will execute tests only in Chromium. You can replace `chromium` with `firefox` or `webkit` for other browsers.
2. Configure the project:
You can set the default browser in your `playwright.config.js` or `playwright.config.ts` file:
```javascript
module.exports = {
projects: [
{
name: 'chromium',
use: {
browser: 'chromium',
},
},
],
};
```
This configures the `chromium` project to use only the Chromium browser by default.
Remember that running tests in parallel can benefit from multiple cores or threads on your machine. If you have limited resources, consider adjusting the number of workers with the `--workers` flag:
```
npx playwright test --project=chromium --browser=chromium --workers=1
```
This will run tests in Chromium with only 1 worker, effectively simulating single-browser execution.
I hope this clarifies how Playwright handles test execution and options for running tests in specific browsers
I have a problem when running "npx playwright test .\tests\example.spec.js" in the new folder it's saying test not found!

Thank you i found the issue, and now i have another problem I launched my test to log in to my app. After filling in the login boxes, it stops at the login screen@@RaghavPal it keeps waiting until the time runs out.
How can i reach you, i have a weird bug@@RaghavPal
There are a few possible reasons why your Playwright test might be stopping at the login screen and waiting until the time runs out:
* The login form is not submitting correctly.
* The login form is submitting, but the response from the server is taking too long to arrive.
* The login form is submitting correctly, but Playwright is not waiting for the login to complete before moving on to the next step in the test.
To resolve this issue, you can try the following:
* Check the console for any errors that might be preventing the login form from submitting correctly.
* Use the `page.waitForNavigation()` method to wait for the page to navigate to the next page after the login form is submitted.
* Use the `page.waitForLoadState()` method to wait for the page to load completely after the login form is submitted.
Here is an example of how to use the `page.waitForNavigation()` method to wait for the page to navigate to the next page after the login form is submitted:
```typescript
import { test, expect } from '@playwright/test';
test('should log in to the app', async ({ page }) => {
await page.goto('example.com/login');
// Fill in the login form.
await page.locator('button[type="submit"]').click();
// Wait for the page to navigate to the next page.
await page.waitForNavigation();
// Verify that the user is logged in.
await expect(page.locator('h1')).toContainText('Welcome, user!');
});
```
Here is an example of how to use the `page.waitForLoadState()` method to wait for the page to load completely after the login form is submitted:
```typescript
import { test, expect } from '@playwright/test';
test('should log in to the app', async ({ page }) => {
await page.goto('example.com/login');
// Fill in the login form.
await page.locator('button[type="submit"]').click();
// Wait for the page to load completely.
await page.waitForLoadState('domcontentloaded');
// Verify that the user is logged in.
await expect(page.locator('h1')).toContainText('Welcome, user!');
});
```

What is the difference between cmd using debug with line number and cmd with specifying the test & debugging. I saw no difference . if no difference what is the use?
Savitha
In Playwright, when it comes to debugging tests, there are two primary methods using the command line:
1. Using `debug` with Line Number:
- Syntax: `npx playwright test --debug /:`
- Purpose: Sets a breakpoint directly on the specified line number within a test file, pausing execution upon reaching that point.
- Advantages:
- Granular control over test execution, allowing you to inspect variables, step through code line by line, and examine the page state at a specific point.
- Useful for isolating complex issues within a single test.
- Disadvantages:
- Requires knowing the exact line number where the problem occurs, which might not always be easy to pinpoint.
- Can be time-consuming for debugging multiple issues or when the exact line is unclear.
2. Specifying the Test & Debugging:
- Syntax: `npx playwright test --debug --grep ""`
- Purpose: Runs the entire test suite or a group of tests matching the provided regular expression, launching the Playwright Inspector for debugging.
- Advantages:
- More efficient for debugging multiple tests or broader issues affecting parts of the test suite.
- Provides an interactive UI for examining page elements, inspecting network requests, and experimenting with changes on the fly.
- Disadvantages:
- Less precise than direct line-number breakpoints, requiring some exploration within the Inspector to diagnose problems.
- Debugging all tests can be slow for large test suites.
Choosing the Right Approach:
- For pinpoint debugging or isolated issues: Use `debug` with line number.
- For broader debugging or issues affecting multiple tests: Specify the test & debug.
Additional Considerations:
- Browser Selection: Use `--browser ` (e.g., `--browser chromium`) to target specific browsers.
- Headless/Headed Mode: Control browser visibility with `--headed` or `--headless`.
- Configuration Overrides: Modify Playwright settings using command-line arguments or a configuration file.
Example:
Suppose you suspect an issue on line 25 of `test_login.spec.ts` within the `login` test:
```bash
npx playwright test --debug login/test_login.spec.ts:25
```
This sets a breakpoint on line 25, allowing you to step through the test execution and investigate the problem in detail.

@@RaghavPal Thanks for the information, I kind of understood , but given the line number for the debug , it has to be the start of test right ? (where we use test as the keyword). I might be wrong , please clarify

Here are the different ways to debug tests and their purposes:
1. Debugging Tests with Line Numbers:
- When you run a test using the command line with a specific line number, Playwright opens the inspector at that exact line in your test file.
- Purpose:
- Allows you to set breakpoints directly in your test code.
- You can step through the test line by line, inspect variables, and analyze the flow.
- Useful for pinpointing issues within a specific test case.
- Command:
```
npx playwright test your-test-file.spec.ts:line-number --debug
```
2. Debugging Tests with Test Name:
- When you specify the test name (instead of a line number), Playwright runs that specific test and opens the inspector.
- Purpose:
- Focuses on a particular test scenario.
- Useful for debugging a specific test without navigating through the entire test file.
- Command:
```
npx playwright test your-test-file.spec.ts --test "Your Test Name" --debug
```
3. Playwright Inspector:
- The Playwright Inspector is a GUI tool that provides a visual interface for debugging.
- Purpose:
- Allows you to step through your tests, live edit locators, pick locators, and see actionability logs.
- Provides a more interactive debugging experience.
- Command:
```
npx playwright test your-test-file.spec.ts --debug
```
- The `--debug` flag opens the inspector.
4. VS Code Extension for Debugging:
- For an even better developer experience, use the VS Code extension for debugging.
- Purpose:
- Debug your tests directly in VS Code.
- Set breakpoints, step through tests, and see error messages.
- Live edit locators and pick locators.
- Benefits:
- Error messages are shown in the editor.
- You can interactively debug your tests.
- Easily switch between different browsers for debugging.
- Use the Playwright Inspector within VS Code.
hii sir, Can we schedule test in playwright ? that test will run automatically on schedule time and will produce report pls guide on this ! thank you
Hi, not aware if there is some in-built feature in playwright, but you can always do this using command line, Can create a batch file having the run commands and can schedule it to run using windows scheduler or any other way
Another option will be to use a CI CD tool like Jenkins
Hello, can you please tell me the cmd to install testrail cli, actually i want to integrate testrail with playwright. can you please help.
Aastha
Absolutely! Integrating TestRail with Playwright using the TestRail CLI is straightforward. Here's how you can do it:
*1. Install TestRail CLI:*
*Prerequisite:* Ensure you have Python 3.10 or higher installed on your system.
*Option 1 (Recommended):* Use pip to install the TestRail CLI:
```
pip install trcli
```
*Option 2 (Alternative):* Download the appropriate wheel file for your operating system from the TestRail CLI releases page ([github.com/gurock/trcli](github.com/gurock/trcli)) and install it manually:
```
python3 -m pip install /path/to/trcli--py3-.whl
```
*2. Configure TestRail CLI:*
* Run `trcli config init` to set up your TestRail configuration.
* Enter your TestRail base URL, username, and password when prompted.
* Optionally, provide a project ID and save the configuration file for future use.
*3. Integrate TestRail with Playwright:*
* Import the `trcli` package in your Playwright test script:
```python
from trcli import Client
# Replace these values with your details
client = Client(base_url="YOUR_TESTRAIL_BASE_URL", username="YOUR_USERNAME", password="YOUR_PASSWORD")
```
* Use the `trcli` client to interact with TestRail throughout your tests:
*Create test runs:*
```python
client.runs.create(project_id=1, name="My Playwright Test Run")
```
*Add test results:*
```python
# For passed tests
client.results.add(run_id=run_id, case_id=1, status=1)
# For failed tests
client.results.add(run_id=run_id, case_id=1, status=5, comment="Test failed due to...")
```
*Get test details:*
```python
test_case = client.tests.get(project_id=1, case_id=1)
print(f"Test Case Title: {test_case['title']}")
```
Hi Raghav, Playwright inspector is not opening when i run the test in debug mode, I am using plawright-1.35.1, do i need to install any extension for it ?
Hi Abhilash
The Playwright inspector should open automatically when you run your tests in debug mode. If it is not opening, there are a few things you can check:
* Make sure that you are using the latest version of Playwright.
* Make sure that you have the `PWDEBUG` environment variable set to `1`.
* Make sure that you are not running your tests in headless mode.
If you have checked all of these things and the Playwright inspector is still not opening, you may need to install the Playwright DevTools extension. This extension is available for Chrome, Firefox, and Edge.
To install the Playwright DevTools extension, follow these steps:
* Open the Chrome Web Store.
* Search for "Playwright DevTools".
* Click on the "Add to Chrome" button.
* Click on the "Add extension" button.
Once the Playwright DevTools extension is installed, you should be able to open the Playwright inspector by pressing `Ctrl`+`Shift`+`I`.
If you are still having trouble opening the Playwright inspector, you can try the following:
* Restart your computer.
* Uninstall and reinstall Playwright.
* File an issue on the Playwright GitHub repository.
I hope this helps
