      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  * }
     30  * </pre>
     31  *
     32  * @see org.junit.Before
     33  * @see org.junit.Test
