Testing multiple activities with espresso

android, android-espresso, testing

Solution

Yes, it is possible. In one of the samples they have demoed this here https://github.com/googlesamples/android-testing/blob/master/ui/espresso/BasicSample/app/src/androidTest/java/com/example/android/testing/espresso/BasicSample/ChangeTextBehaviorTest.java

@Test
public void changeText_newActivity() {
    // Type text and then press the button.
    onView(withId(R.id.editTextUserInput)).perform(typeText(STRING_TO_BE_TYPED),
            closeSoftKeyboard());
    onView(withId(R.id.activityChangeTextBtn)).perform(click());

    // This view is in a different Activity, no need to tell Espresso.
    onView(withId(R.id.show_text_view)).check(matches(withText(STRING_TO_BE_TYPED)));
}

Read the inline comment.

Waiting for the new activity to load is taken care of implicitly by Espresso.

Problem

Is it possible to write tests across several activities using the android espresso framework?
