guice java.lang.ClassCastException: Object_Proxy cannot be cast to android.net.ConnectivityManager

Question

Hello I am using RoboGuice and Mockito in my project I am facing problems resolving SystemServices in test...

I made a class

public class RoboInstrumentationTestCase extends InstrumentationTestCase {

protected Application application;
protected Context context;
protected Injector injector;

@Override
protected void setUp() throws Exception {
    application = mock(Application.class, RETURNS_DEEP_STUBS);
    context = mock(RoboActivity.class, RETURNS_DEEP_STUBS);
    injector = RoboGuice.setBaseApplicationInjector(application, RoboGuice.DEFAULT_STAGE, 
            Modules.override(RoboGuice.newDefaultRoboModule(application)).
            with(   new UtilModule(),
                    new DatabaseModule(), 
                    new FixtureModule(),
                    new RepositoryModule(),
                    new ServiceCoreModule(),
                    new ServiceModule()
                    ));
    when(context.getApplicationContext()).thenReturn(application);
    when(application.getApplicationContext()).thenReturn(application);

    super.setUp();
}

@Override
protected void tearDown() throws Exception {
    super.tearDown();
    RoboGuice.util.reset();
}

protected Injector getInjector() {
    return injector;
}
}

and in other class I need to retrieve the ConnectivityManager

public class ConnectivityUtilImpl implements ConnectivityUtil {

private ConnectivityManager connectivityManager;

@Inject
public void setConnectivityManager(ConnectivityManager connectivityManager) {
    this.connectivityManager = connectivityManager;
}

/* (non-Javadoc)
 * @see com.devsu.supermaxi.util.impl.ConnectivityUtil#getNetworkInfo(android.content.Context)
 */
@Override
public NetworkInfo getNetworkInfo(){
    return connectivityManager.getActiveNetworkInfo();
}

But I get the following error:

May I suggest a "keep it simple" approach, just keep a mock of `ConnectivityManager` and `NetworkInfo` and that's all you need to test this class — , Jan 20 '14 at 20:36
Thank you very much, you are right.. i will fallow your suggestion — Darien Alvarez, Jan 21 '14 at 12:31
