While going through the series of Selenium Webdriver tutorials, we are introducing in this tutorial about Testng and the different methods to install TestNG in Eclipse for Selenium WebDriver. Before going to the installation process, let’s begin with what the TestNG is and why to use TestNG with Selenium WebDriver.

TestNG is an open source automation testing framework which was inspired by JUnit that uses annotations for managing test cases more efficiently. In TestNG, “NG” means Next Generation, so it was the testing framework built for the next generation that eliminates most of the limitations of the older testing frameworks like JUnit and NUnit. TestNG allows the testers to write more powerful and flexible tests than other testing frameworks.

Why Use TestNG With Selenium WebDriver

Since, selenium WebDriver have some limitations for generating test results, managing and running the test. Using TestNG with selenium WebDriver can overcome all the limitations of using default selenium. Following are the most important features and advantages of using TestNG with selenium.

1. It can generate the test report in a proper format that includes all the details on how many number of test cases are passed, failed and skipped after executing the test script.
2. Since, it supports using annotations(@), we can easily manage the test scripts and able to set the priority for running the test cases.
3. It introduces the test groups, so we can group multiple test cases by converting them into testing.xml file.
4. Due to its flexible run-time configuration feature, we can execute test cases multiple times without using loops.
