17. ITestListener in testNg

The ITestListener interface in TestNG is a powerful tool used for implementing custom listeners to observe and intercept the test execution lifecycle events. By implementing this interface, developers can create customized behaviors and actions before and after certain test-related events occur.Key Features of ITestListener:Interface Methods:onTestStart(ITestResult result): Invoked before each test method starts execution.onTestSuccess(ITestResult result): Triggered after a test method successfully completes execution.onTestFailure(ITestResult result): Called when a test method fails during execution.onTestSkipped(ITestResult result): Executed when a test method is skipped.onTestFailedButWithinSuccessPercentage(ITestResult result): Fired after a test method fails but is within the success percentage defined in the testng.xml.onStart(ITestContext context): Invoked before the test suite starts execution.onFinish(ITestContext context): Called after the test suite finishes execution.Custom Actions:By implementing these methods, developers can define custom actions such as logging, taking screenshots on test failures, setting up or tearing down test environments, sending notifications, etc.Test Context:The ITestContext parameter in onStart and onFinish methods provides information about the test suite, like the suite name, test methods, and other configurations.Benefits:Customization: Allows for tailored actions and behaviors based on test events.Logging and Reporting: Facilitates enhanced logging and reporting mechanisms.Error Handling: Enables handling test failures and exceptions gracefully.By leveraging the ITestListener interface, testers and developers can create flexible and customizable test execution workflows, enhancing test reporting and enabling efficient handling of test outcomes and exceptions within the TestNG framework.ABOUT OUR CHANNELOur channel is about transforming yourself from a manual test engineer to SDET. We have already covered lots of cool stuff such as Linux, Functional Programming and Streams in Java, Docker selenium Integration and new contents are added regularly. If you have already completed courses for automation tools like selenium and rest assured and still find SDET interviews are tough or you are missing real time use cases and scenarios then this channel is your go- to resource.Check out our channel here:   / @qaautomationclassesdon’t   forget to subscribe!CHECK OUT OUR OTHER PlaylistFunctional Programming in Java - Unlock the Power of Functional Paradigm:https://youtube.com/playlist?list=PLt...
