JUNIT4 Test case annotations.

‘@Before ‘ :

In JUnit4 @Before is used to execute set of preconditions before executing a test. 

“@After “ :

Method that is marked with @After gets executed after execution of every test. 

“@BeforeClass” :

If a JUnit test case class contains lot of tests which all together need a method which sets up a precondition and that needs to be executed before executing the Test Case class then we can utilize “@BeforeClass” annotation.

“@AfterClass” :

In the same way “@AfterClass” annotation can be used to execute a method that needs to be executed after executing all the tests in a JUnit Test Case class.

“@Test” :

Write you function call in the test method.
