Features :
*JUnit is an open source framework used for writing & running tests.
*Provides Annotation to identify the test methods.
*Provides Assertions for testing expected results.
*Provides Test runners for running tests.
*JUnit tests allow you to write code faster which increasing quality
*JUnit is elegantly simple. It is less complex & takes less time.
*JUnit tests can be run automatically and they check their own results and provide
immediate feedback. There's no need to manually comb through a report of test results.
*JUnit tests can be organized into test suites containing test cases and even other test
suites.
