Lesson d2: Halloween pumpkins
This is a video from a free lesson in my online course teaching test-driven development using Cypress where I code a small web calculator cypress.tips/courses/tdd-calculator In this lesson, we replace the orange operator button backgrounds with an image of a pumpkin. We confirm the image is downloaded by the browser, it is applied via the CSS property "background-image" plus the button becomes larger when the user hovers over it. Check out the full course if you want to see more lessons or do the hands-on exercises. Until Nov 11th, 2024 you can use the promo code TDDHALLOWEEN to get 25% off this course.

Same Height
มุมมอง 291หลายเดือนก่อน
This video shows Cypress test that confirms that the element does not change its height after some user action. You need to compare heights as numbers and with a tolerance. Find the full recipe at glebbahmutov.com/cypress-examples/
Vertical Center
มุมมอง 307หลายเดือนก่อน
This video shows how the Cypress test can confirm the vertical alignment of two elements. We get the bounding client rectangle from both elements and then compare the centers' values. We use "closeTo" assertion since floating-point values might disagree by a tiny amount. We can simplify the test using "cypress-map" plugin and even make the entire chain retryable. Find the source code at glebbah...
Test Layout Shift
มุมมอง 4142 หลายเดือนก่อน
This video shows how you can detect even 1 pixel layout shifts during testing. All you need is to "remember" the starting "offsetTop / offsetLeft" properties and then check them again after interacting with the page. Find the full recipe at glebbahmutov.com/cypress-examples/
Find Elements Without An Attribute
มุมมอง 6502 หลายเดือนก่อน
This video shows how to find all the elements that do not have a specific attribute. For example, let's find all buttons that don't have attribute "data-cy" cy.get("button:not([data-cy])") Find the recipe at glebbahmutov.com/cypress-examples
Retry Network Requests
มุมมอง 5592 หลายเดือนก่อน
This video shows how to use plugins cypress-recurse and cy-spok to retry calling the backend until it responds with the expected result. Read the blog post glebbahmutov.com/blog/retry-network-requests/ for all source code. Find the plugins at github.com/bahmutov/cypress-recurse and github.com/bahmutov/cy-spok
Parse The Account Number Explained
มุมมอง 4362 หลายเดือนก่อน
This video solves a Cypress test problem the user asked. The application shows an account number: a 9-digit number. The test should wait for the number and then compare its value. I explain the problem with the initial solution and then show how to write this test. Find the full code at glebbahmutov.com/cypress-examples/recipes/parse-account-number.html
Skip Dependent Cypress Tests On Failure
มุมมอง 6372 หลายเดือนก่อน
If your Cypress tests depend on each other, if a test fails, all tests after that fail. I wrote a plugin github.com/bahmutov/cypress-skip-this-test that automatically skips the tests if any of the previous tests in the same suite fails. This video shows the plugin in action. For more details, see the blog post glebbahmutov.com/blog/skip-dependent-tests-on-failure/
Testing window.close Method From Cypress
มุมมอง 5513 หลายเดือนก่อน
This video shows how to set a "window.close" method stub using cy.window and cy.stub method calls. Then we can click on the button and confirm the method call was indeed made. Find the full code at glebbahmutov.com/cypress-examples
Check If All Images Have Loaded Using cy.each Command
มุมมอง 6474 หลายเดือนก่อน
You can check multiple images on the page to verify they load using Cypress "cy.get(...).each" command. Inside, you can verify the property "naturalWidth" or "naturalHeight" and if it is above zero, then the image has loaded. expect($el, `image ${k 1}`) .to.have.prop('naturalWidth') .be.greaterThan(0) You can find the full source code at glebbahmutov.com/cypress-examples/
Run Just The Last Failed Tests Using cypress-plugin-last-failed

cy.root Command Example

Refactor Cypress Api Tests Part 4: Use deep.include Assertion
มุมมอง 5355 หลายเดือนก่อน
In this video, I refactor the user spec tests. We will combine multiple tests into a single one using "deep.include" assertion to check one or many known properties of an object. Then we will improve the page object method, and then I will switch to use cy-spok plugin to simplify checking nested properties. Find the code in the branch "refactor-user-spec" of the repo github.com/bahmutov/cypress...
Refactor Cypress Api Tests Part 3: Use cypress-map
มุมมอง 6365 หลายเดือนก่อน
In this video, I simplify the tests and the "beforeEach" hooks using query commands from the cypress-map plugin. Find the starting code in the repo github.com/bahmutov/cypress-conduit-api and the cypress-map plugin documentation in the repo github.com/bahmutov/cypress-map

    Hy I knew I have some different question other than above video content. I was using cypress from 2 months daily implementing test scenarios and running. But today when i ran my previous test cypress automatically while running test removed my web application( for which I'm running test cases) Basic settings of user with whom i was logged in.. But if do manually in my browser the same test do nothing extra. But in cypress it is doing some extra work on my app which i don't know y?

    Hello Gleb, Thanks for sharing information on cypress. I am blocked on below scenario: Using : POM File 1: TC_001.cy.ts is having a method -- > createPayment() File 2: POM_paymentActions.js createPayment(){ //other steps this.verifyPaymentSaveMsg(expectedMsg) //other steps } verifyPaymentSaveMsg(expectedMsg){ //here is have a list of error message to be NOT to be displayed and then expectedMsg to be there Problem: i want to handle and SKIP the it block from my TC_001.cy.ts file IF the error was here AS payment step should not make the test case failed. If there is an error on this step, just stop next steps and skip the testcase exection, how will i send false or somthing from here that will roll back my createPayment() and then the TC_001.cy.ts will be skipped. } PS: we are not verifying payment part in our automation , but we just have to add that step in the test case becuase we cannot perform next steps and the payment failure is mostly due to setup issue (its a 3rd party service being tested by some other team)
