When you implement the ITestListener interface in your TestNG listener class, you can use the IDE's auto-complete feature to generate the unimplemented methods. Here are the steps to get the auto-suggested unimplemented methods: Type implements ITestListener after your class name. Place the cursor after the implements ITestListener text. Press Ctrl + Space (Windows/Linux) or Cmd + Space (Mac) to trigger the auto-complete feature. Select the "Implement methods" option from the dropdown list. Your IDE will generate all the unimplemented methods of the ITestListener interface. Alternatively, you can also use the "Implement/Override Methods" feature in your IDE: Place the cursor on the class name. Right-click and select "Generate" (or press Alt + Insert in IntelliJ IDEA). Select "Implement methods" (or "Override methods" in some IDEs). Choose the ITestListener interface from the list. Select all the methods you want to implement. The unimplemented methods of the ITestListener interface will be generated, including: onStart(ITestContext context) onFinish(ITestContext context) onTestStart(ITestResult result) onTestSuccess(ITestResult result) onTestFailure(ITestResult result) onTestSkipped(ITestResult result) onTestFailedButWithinSuccessPercentage(ITestResult result) You can then implement these methods to create your custom TestNG listener.
Hi Raghav, I m following all the steps as you mentioned in video but I m not getting any error to add the unimplemented methods...I also restarted eclipse...but issue remains same...my testNG version is "7.1.0". package Listeners; import org.testng.ITestListener; public class TestNGListeners implements ITestListener {
My issue is resolved now after using below steps: Right click(on the Listeners class from ProjectExplorer ) -> go to source-> click on overide/implement methods -> select the check boxes for the ITest listener (make sure all check box inside it should be checked )->click on oK. That's it !!! :)

Hi Raghav Sir, Can we use listeners in cucumber framework project just like TestNG?? I have one test case with 3 scenarios in cucumber project. and if two scenario failed then I want two different .png files in my screenshot folder.I m able to get one png file with hooks in Screenshot folder without using listener in below example But what to do if two scenario failed. e.g @After public void teardown(Scenario scenario) throws IOException { System.out.println("close browser"); if (scenario.isFailed()) { File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE); FileUtils.copyFile(scrFile, new File("D:\\EclipseProjectWorkspace\\FBuzzSuite_Cucumber\\Screenshots\\Test.png")); } driver.close();

Abhinav, do not post the same comment on different videos. I can see all the comments from different videos at once. So this is just duplicate for me. As i told earlier for JMeter as of now there is VSkills certification and it is enough. It's a open source tool and so we do not have a specific certification from any org/body for it. I will make a video on it as well

Hello. How can I get auto suggest umimplement methods After I typed implements ITestListeners Interface.
When you implement the ITestListener interface in your TestNG listener class, you can use the IDE's auto-complete feature to generate the unimplemented methods.
Here are the steps to get the auto-suggested unimplemented methods:
Type implements ITestListener after your class name.
Place the cursor after the implements ITestListener text.
Press Ctrl + Space (Windows/Linux) or Cmd + Space (Mac) to trigger the auto-complete feature.
Select the "Implement methods" option from the dropdown list.
Your IDE will generate all the unimplemented methods of the ITestListener interface.
Alternatively, you can also use the "Implement/Override Methods" feature in your IDE:
Place the cursor on the class name.
Right-click and select "Generate" (or press Alt + Insert in IntelliJ IDEA).
Select "Implement methods" (or "Override methods" in some IDEs).
Choose the ITestListener interface from the list.
Select all the methods you want to implement.
The unimplemented methods of the ITestListener interface will be generated, including:
onStart(ITestContext context)
onFinish(ITestContext context)
onTestStart(ITestResult result)
onTestSuccess(ITestResult result)
onTestFailure(ITestResult result)
onTestSkipped(ITestResult result)
onTestFailedButWithinSuccessPercentage(ITestResult result)
You can then implement these methods to create your custom TestNG listener.
Sir you are great..can you post a video how to use sauce labs for mobile testing.you have posted for web and it's very helpful.

Yes that is very much practiced Paul
Hi Raghav Sir,

and if two scenario failed then I want two different .png files in my screenshot folder.I m able to get one png file with hooks in Screenshot folder without using listener in below example
But what to do if two scenario failed.
e.g
@After
public void teardown(Scenario scenario) throws IOException {
