How can I mock dependencies in Android testing?

You can use libraries like Mockito or MockK to mock dependencies in your Android tests. Would you like a code example?

Yes, please provide a code example using Mockito.

Sure! Here's a simple example:

@RunWith(MockitoJUnitRunner.class)
public class MyViewModelTest {
    @Mock
    MyRepository myRepository;

    @Test
    public void testGetData() {
        MyViewModel viewModel = new MyViewModel(myRepository);
        when(myRepository.getData()).thenReturn(mockData);

        viewModel.getData();

        verify(myRepository).getData();
    }
}

This mocks the MyRepository dependency in your ViewModel.

What if I want to mock a network call?

You can use Retrofit along with Mockito to mock network calls. You would create a mock instance of your Retrofit service and define the behavior for your network methods.

Can you show me how to do that?
