Annotation Type BeforeClass


@Retention(value=RUNTIME)
@Target(value=METHOD)
public @interface BeforeClass

Sometimes several tests need to share computationally expensive setup (like logging into a database). While this can compromise the independence of tests, sometimes it is a necessary optimization. Annotating a public static void no-arg method with @BeforeClass causes it to be run once before any of the test methods in the class. The @BeforeClass methods of superclasses will be run before those the current class.

For example:
 public class Example {
    @BeforeClass public static void onlyOnce() {
       ...
    }
    @Test public void one() {
       ...
    }
    @Test public void two() {
       ...
    }
 }
