/**
 * Returns a collection of classes whose non-abstract methods should always be replaced with
 * no-ops. By default, this list includes {@link Composite}, {@link DOM} {@link UIObject},
 * {@link Widget}, {@link Image}, and most subclasses of {@link Panel}. It will also include any
 * classes specified via the {@link WithClassesToStub} annotation on the test class. This makes
 * it much safer to test code that uses or extends these types.
 * <p>
 * This list can be customized via {@link WithClassesToStub} or by defining a new test runner
 * extending {@link GwtMockitoTestRunner} and overriding this method. This allows users to
 * explicitly stub out particular classes that are causing problems in tests. If you override this
 * method, you will probably want to retain the classes that are stubbed here by doing something
 * like this:
 *
 * <pre>
 * &#064;Override
 * protected Collection&lt;Class&lt;?&gt;&gt; getClassesToStub() {
 *   Collection&lt;Class&lt;?&gt;&gt; classes = super.getClassesToStub();
 *   classes.add(MyBaseWidget.class);
 *   return classes;
 * }
 * </pre>
 *
 * @return a collection of classes whose methods should be stubbed with no-ops while running tests
