/**
 * 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.
 * 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
