What are Advantages of Testing with JUnit?

1. Quick and easy generation of test cases and test data.
2. Ability to reuse the older test cases as well as the test data for making a new test case.
3. Generate test cases which stick on to their previous test values.
4. Promote TDD, i.e. Test Driven Development
5. Enhance productivity and reduce production cost.
6. Excellent and highly comprehensive reporting technique.
7. Easy contrast between expected output and the output displayed on the console.
8. Logical aggregation of test cases.
9. Add the JUnit.jar package in the class path environment variable of you system.
10. Make a subclass of “TestCase”.
11. In the subclass, define the actual test method you want to add. You may add multiple test methods.
12. In the above methods write the assert methods.
13. Test methods are declared public and have a void return type because they do not actually return a value after their execution.
14. They have standard naming system with the name string pattern as “testXYZ”.
15. XYZ in the naming pattern is the generic name for the target class on which the test is to be executed.

Test methods normally do not include any arguments.
