How To Tell Junit/mockito To Wait For Androidannotations To Inject The Dependenices

I am using AndroidAnnotations in my project and I want to test a presenter. The test suite runs and @Test methods are apparently called before the injection has finished, because I

Solution 1:

AndroidAnnotations works by creating subclasses of the annotated classes, and adds boilerplate code in them. Then when you use your annotated classes, you will swap the generated classes in either implicitly (by injecting) or explicitly (by accessing a generated class, for example starting an annotated Activity).

So in this case to make it work, you should have run the annotation processing on the test class LoginPresenterTest, and run the test only on the generated LoginPresenterTest_ class. This can be done, but i suggest a cleaner way:

@RunWith(MockitoJUnitRunner.class)publicclassLoginPresenterTest {

    private LoginPresenter loginPresenter;

    @Mockprivate LoginView loginView;

    @BeforevoidsetUp() {
        // mock or create a Context object
        loginPresenter = LoginPresenter_.getInstance_(context);
    }

    @TestpublicvoidwhenUserNameIsEmptyShowErrorOnLoginClicked()throws Exception {
        when(loginView.getUserName()).thenReturn("");
        when(loginView.getPassword()).thenReturn("asdasd");
        loginPresenter.onLoginClicked();
        verify(loginView).setEmailFieldErrorMessage();
    }
}

So you have a normal test class, and you instantiate the generated bean by calling the generated factory method.
