/**
* 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 {@link org.junit.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() { * ... * } * } ** * @see org.junit.BeforeClass * @see org.junit.After * @since 4.0 */ @Retention(RetentionPolicy.RUNTIME) @Target(ElementType.METHOD) public @interface Before { }
