Question

What are the advantages of TestNG over JUnit framework?

Answer 1

Hey Kimberly, TestNG has many advantages over JUnit testing framework:

1. TestNG Annotations are easy to understand over JUnit.
2. No constraints like declaring @BeforeClass and @AfterClass in TestNG, which are present in JUnit.
3. As method name constraint is present in JUnit, such method name constraint is not present in TestNG and you can specify any test method names.
4. TestNG enables you to group test cases easily which is not possible in JUnit.
5. TestNG supports following three 3 additional setUp/tearDown level: @Before/AfterSuite, @Before/AfterTest and @Before/AfterGroup.
6. TestNG do not require extend any class. 
7. TestNG allows to execute test cases based on group which isn't possible in JUnit.
8. Parallel execution of Selenium test cases is possible in TestNG.
