In this tutorial, I will show you how to install TestNG in Eclipse in multiple ways. TestNG is a testing framework designed for the Java programming language. The framework is inspired by JUnit and NUnit. It is a cutting edge test automation tool that overcomes the limitation in the JUnit framework. In its initial era, it was only used in unit testing of the Java projects during the development phase.
However, nowadays it has become very popular amongst the testing fraternity because of its rich feature. TestNG plays an instrumental role in the test script development as well as test suite creation and execution. Some of its cool features are TestNG annotations, test case management, parallel execution, effective reporting, and much more.
