Annotation Type Before


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

When writing tests, it is common to find that several tests need similar objects created before they can run. Annotating a public void method with @Before causes that method to be run before the Test method. The @Before methods of superclasses will be run before those of the current class. No other ordering is defined.

Here is a simple example:
 public class Example {
    List empty;
    @Before public void initialize() {
       empty= new ArrayList();
    }
    @Test public void size() {
       ...
    }
    @Test public void remove() {
       ...
    }
 }
