009     * If you allocate expensive external resources in a {@link org.junit.BeforeClass} method you need to release them
010     * after all the tests in the class have run. Annotating a <code>public static void</code> method
011     * with <code>&#064;AfterClass</code> causes that method to be run after all the tests in the class have been run. All <code>&#064;AfterClass</code>
012     * methods are guaranteed to run even if a {@link org.junit.BeforeClass} method throws an
013     * exception. The <code>&#064;AfterClass</code> methods declared in superclasses will be run after those of the current
014     * class, unless they are shadowed in the current class.
015     * <p>
016     * Here is a simple example:
017     * <pre>
018     * public class Example {
019     *    private static DatabaseConnection database;
020     *    &#064;BeforeClass public static void login() {

022     *    }
023     *    &#064;Test public void something() {
