+/**
+ * <p>If you allocate expensive external resources in a {@link org.junit.BeforeClass} method you need to release them
+ * after all the tests in the class have run. Annotating a <code>public static void</code> method
+ * 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>
+ * methods are guaranteed to run even if a {@link org.junit.BeforeClass} method throws an 
+ * exception. The <code>&#064;AfterClass</code> methods declared in superclasses will be run after those of the current
+ * class.</p>
+ * 
+ * Here is a simple example:
+* <pre>
+ * public class Example {
+ *    private static DatabaseConnection database;
+ *    &#064;BeforeClass public static void login() {
+ *          database= ...;
+ *    }
+ *    &#064;Test public void something() {
+ *          ...
+ *    }
+ *    &#064;Test public void somethingElse() {
+ *          ...
+ *    }
+ *    &#064;AfterClass public static void logout() {
+ *          database.logout();
+ *    }
+ * }
+ * </pre>
+ * 
+ * @see org.junit.BeforeClass
+ * @see org.junit.Test
