Gwt Mockito: @RunWith(GwtMockitoTestRunner.class) causes Exception

I'm doing a project with gwt at the moment. I have to test a presenter using Eclipse Luna, JUnit and Mockito and have problems doing anything.

After I failed with mockito I discovered GwtMockito and tried that. I used this example to get started: Github GwtMockito example

My Test class looks like this:

@RunWith(GwtMockitoTestRunner.class)
public class GamePresenterTest {

@GwtMock private GameServiceAsync gameService;
@GwtMock private LobbyPresenter lobbyPresenter;
@GwtMock private EventBus eventBus;
@GwtMock private Display gameView;
@GwtMock private User user;
@GwtMock private Player player;
@GwtMock private ClickEvent event;

private GamePresenter presenter;
private String username = "name";
private String gameTitle = "title";

@Before
public void setUp() {
    System.out.println("TODO: set up");
}

@Test
public void testActionTableClicked() {
    System.out.println("TODO: add test");
}
}

When I run it I get this

        ... 18 more

When I remove the @RunWith(GwtMockitoTestRunner.class) I get another message that tells me I should use initMocks, but I don't how to do that, too. Without @RunWith(GwtMockitoTestRunner.class) and the @GwtMock stuff everything works fine of course.

I hope someone can help, because my project ends in a few weeks.

Looks like you need javassist-<version>.jar. Add it to your classpath and it should work
