Anyone who knows or has resolved please help me. Thank you very much!

Note this case below:

import static android.support.test.espresso.Espresso.onView;
import static android.support.test.espresso.action.ViewActions.typeText;
import static android.support.test.espresso.assertion.ViewAssertions.matches;
import static android.support.test.espresso.matcher.ViewMatchers.withId;
import static android.support.test.espresso.matcher.ViewMatchers.withText;

// Testes para MapsActivity
public class MapsActivityInstrumentationTest {

    @Rule
    public ActivityTestRule<MainActivity> activityTestRule =
            new ActivityTestRule<>(MapsActivity.class);

     // Verifica se no EditText tem o texto "Hello"
    @Test
    public void validaEditText() {
        onView(withId(R.id.etInput)).perform(typeText("Hello")).check(matches(withText("Hello")));
    }
}

build.Gradle

android {
    ...
    defaultConfig {
        ...
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
}

For more details, take a read in this article.

You can check out a list of Espresso methods on google documentation.
