    009     * If you allocate external resources in a {@link org.junit.Before} method you need to release them
    010     * after the test runs. Annotating a <code>public void</code> method
    011     * with <code>&#064;After</code> causes that method to be run after the {@link org.junit.Test} method. All <code>&#064;After</code>
    012     * methods are guaranteed to run even if a {@link org.junit.Before} or {@link org.junit.Test} method throws an
    013     * exception. The <code>&#064;After</code> methods declared in superclasses will be run after those of the current
    014     * class, unless they are overridden in the current class.
    015     * <p>
    016     * Here is a simple example:
    017     * <pre>
    018     * public class Example {
    019     *    File output;
    020     *    &#064;Before public void createOutputFile() {
    021     *          output= new File(...);
    022     *    }
    023     *    &#064;Test public void something() {
    024     *          ...
    025     *    }
    026     *    &#064;After public void deleteOutputFile() {
    027     *          output.delete();
    028     *    }
