9    * <p>If you allocate external resources in a {@link org.junit.Before} method you need to release them
10   * after the test runs. Annotating a <code>public void</code> method
11   * with <code>&#064;After</code> causes that method to be run after the {@link org.junit.Test} method. All <code>&#064;After</code>
12   * methods are guaranteed to run even if a {@link org.junit.Before} or {@link org.junit.Test} method throws an 
13   * exception. The <code>&#064;After</code> methods declared in superclasses will be run after those of the current
14   * class.</p>
15   * 
16   * Here is a simple example:
17  * <pre>
18   * public class Example {
19   *    File output;
20   *    &#064;Before public void createOutputFile() {
21   *          output= new File(...);
22   *    }
23   *    &#064;Test public void something() {
24   *          ...
25   *    }
26   *    &#064;After public void deleteOutputFile() {
27   *          output.delete();
28   *    }
29   * }
