TestNG Tutorial with Selenium

testng tutorial

TestNG is a testing framework inspired by JUnit and NUnit. But introducing some new functionality that makes it more powerful and easier to use.

It is an open-source automated testing framework; where NG of TestNG means Next Generation. TestNG is similar to JUnit but it is much more powerful than JUnit but still, it’s inspired by JUnit. It is designed to be better than JUnit, especially when testing integrated classes. Pay special thanks to Cedric Beust who is the creator of TestNG.

This eliminates most of the limitations of the older framework. It provides the developer the ability to write more flexible and powerful tests with help of easy annotations, grouping, sequencing & parametrizing.
