Annotation Type Before

@Retention(RUNTIME)
@Target(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, unless they are overridden in 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() {
      ...
   }
}
