• TESTNG listeners can be used to perform actions before or after a test method, class, suite, or all tests.

• Listeners can be used to generate logs, take screenshots, or perform any custom actions during test execution.

• Some commonly used listeners in TESTNG are IInvokedMethodListener, ITestListener, and ISuiteListener.
