Espresso - How can I check if an activity is launched after performing a certain action?

Question

    public void testLoginAttempt() {
        Espresso.onView(ViewMatchers.withId(R.id.username)).perform(View         


        

Answer 1

You can use:

intended(hasComponent(YourExpectedActivity.class.getName()));

Requires this gradle entry:

androidTestCompile ("com.android.support.test.espresso:espresso-intents:$espressoVersion")

The import for the intended() and hasComponent()

import static android.support.test.espresso.intent.Intents.intended;
import static android.support.test.espresso.intent.matcher.IntentMatchers.hasComponent;

as mentioned by Shubam Gupta please remember to call Intents.init() before calling intended(). You can eventually call it in the @Before method.
