Listeners Interface in TestNG Framework

The video tutorial explains the concept of TestNG listeners, their implementation, and practical usage in automation testing. It covers how listeners can be used to reroute execution upon test failures, allowing for actions like taking screenshots or logging responses. The tutorial provides a step-by-step guide on implementing listeners using the ITestListener interface, configuring them in TestNG XML files, and testing their functionality. The video aims to give a clear understanding of how listeners work and their benefits in a testing framework.
