Interface AfterClass

public interface AfterClass

If you allocate expensive external resources in a BeforeClass method you need to release them after all the tests in the class have run. Annotating a public static void method with @AfterClass causes that method to be run after all the tests in the class have been run. All @AfterClass methods are guaranteed to run even if a BeforeClass method throws an exception. The @AfterClass methods declared in superclasses will be run after those of the current class. Here is a simple example:
 public class Example {
    DatabaseConnection database;
    @BeforeClass public void login() {
          database= ...;
    }
    @Test public void something() {
          ...
    }
    @Test public void somethingElse() {
          ...
    }
    @AfterClass public void logout() {
          database.logout();
    }
 }
