What is TestNG FrameWork?
1. TestNG is the most widely used testing framework in the software testing industry. It is an open source automated Testing framework.
2. TestNG is an automation testing framework in which NG stands for “Next Generation”.
3. TestNG is used for different kinds of testing like unit, functional, integration testing, end-to-end and etc.
4. TestNG is inspired by JUnit which uses the annotations (@).
5. TestNG allows you to group the test cases easily which is helpful if you want to run specific test cases.
Example, Let’s consider a scenario where we have created two groups such as ‘Smoke’ and ‘Regression’. If you want to execute the test cases in a ‘Regression’ group, then this can only be possible in the TestNG framework.
6. TestNG provides more powerful and flexible test cases with help of easy annotations, grouping, sequencing and parametrizing.
7. TestNG produces HTML reports for implementation.
8. TestNG can generate a proper report, and you can easily get the exact report of many test cases are passed, failed and skipped.
9. TestNG allows you to execute test cases parallelly i.e multiple test cases can be run in the TestNG framework.
