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

you can create own testrule

public class MyCustomRule extends ActivityTestRule {
    public MyCustomRule(Class activityClass) {
        super(activityClass);
    }

    @Override
    protected void beforeActivityLaunched() {
        super.beforeActivityLaunched();
        // Maybe prepare some mock service calls
        // Maybe override some depency injection modules with mocks
    }

    @Override
    protected Intent getActivityIntent() {
        Intent customIntent = new Intent();
        // add some custom extras and stuff
        return customIntent;
    }

    @Override
    protected void afterActivityLaunched() {
        super.afterActivityLaunched();
        // maybe you want to do something here 
    }

    @Override
    protected void afterActivityFinished() {
        super.afterActivityFinished();
        // Clean up mocks
    }
}

and set as ActivityTestRule

@Rule
public ActivityTestRule testRule = new MyCustomRule<>(MainActivity.class);

in beforeActivityLaunched() you can then inject your viewModelFactory
