Problem with @Spy annotations

[syrinx2012]

I get the error below when trying to run the following test using Maven. I have used the mockito @SPY annotation many times before and never got this issue. In the past however, my unit tests would always reside within frameworks.. Somehow this type of test doesn't run if the model is part of an external framework used is by the application.

@RunWith(MockitoJUnitRunner.class)
public class BasicTest {

    @Rule
    public MockEditingContext   _editingContext = new MockEditingContext("ModelName");

    @Dummy
        @Spy
    Membre                      membre;

    @Test
    public void test() {
        assertTrue(true);
    }

}

test(com.acaiq.certification.controleur.ControleurFusionTest) Time elapsed: 1.121 sec <<< ERROR!
