Espresso, Dagger2 set ViemodelProvider.Factory on BaseActivity

Question

I have an abstract AccountRequiredActivity that looks like this (and works fine):

public abstract class AccountRequiredActivity extends LifecycleActivity {
         


        

Answer 1

I solved the problem by overriding AndroidInjector's inject() method:

@Override
public AndroidInjector activityInjector() {
    return new AndroidInjector() {
        @Override
        public void inject(Activity instance) {
            AccountViewModel viewModel = mock( AccountViewModel.class );
            if(instance instanceof TestHomeActivity) {
                ((TestHomeActivity) instance).viewModelFactory = ViewModelUtil.createFor( viewModel );
            }
        }
    };
}
