What is the use of @Listener annotation in TestNG?

Hey Macy

Listeners are used for performing some action in case an event gets triggered. Usually, testNG listeners are used for configuring reports and logging. One of the most widely used listeners in testNG is the ITestListener interface.

It has methods like onTestSuccess, onTestFailure, onTestSkipped, etc. We need to implement this interface by creating a listener class of our own. After that using the @Listener annotation, we can specify that for a particular test class, a customized listener class should be used.

@Listeners(PackageName.CustomizedListenerClassName.class)
public class TestClass { 
    WebDriver driver= new FirefoxDriver();
    
    @Test 
    public void testMethod(){
    //test logic
    }
}
