Android: базовый тест с эспрессо

Я пытаюсь добавить базовый тест эспрессо в свое приложение для Android. Мой тестовый файл (расположенный в папке androidTest / java) был создан функцией «запись теста эспрессо» и выглядит следующим образом:

package info.my_xxxx.activities;

@RunWith(AndroidJUnit4.class)
public class AdviceDisplay2 {

    @Rule
    public IntentsTestRule<SplashActivity> mActivityTestRule = new IntentsTestRule<>(SplashActivity.class);

    @Test
    public void adviceDisplay2() {
        // Added a sleep statement to match the app's execution delay.
        // The recommended way to handle such scenarios is to use Espresso idling resources:

        try {
            Thread.sleep(10000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        ViewInteraction appCompatImageView = onView(
                allOf(withId(R.id.third_button),
                        childAtPosition(
                                allOf(withId(R.id.linear_layout),
                                        childAtPosition(
                                                withId(R.id.bottom_button),
                                                0)),
                                2),
                        isDisplayed()));
        appCompatImageView.perform(click());

        ViewInteraction textView = onView(
                allOf(withId(R.id.advice),
                        childAtPosition(
                                allOf(withId(R.id.RelativeLayout01),
                                        childAtPosition(

                                                0)),
                                1),
                        isDisplayed()));
        textView.check(matches(isDisplayed()));

    }

    private static Matcher<View> childAtPosition(
            final Matcher<View> parentMatcher, final int position) {

        return new TypeSafeMatcher<View>() {
            @Override
            public void describeTo(Description description) {
                description.appendText("Child at position " + position + " in parent ");
                parentMatcher.describeTo(description);
            }

            @Override
            public boolean matchesSafely(View view) {
                ViewParent parent = view.getParent();
                return parent instanceof ViewGroup && parentMatcher.matches(parent)
                        && view.equals(((ViewGroup) parent).getChildAt(position));
            }
        };
    }
}

Как видите, это просто щелчок по представлению и проверка, существует ли представление или нет ... Мой файл gradle (уровень модуля):

Кажется, все зависимости в порядке, но при запуске теста из студии Android через несколько минут я получил это сообщение:

Тесты завершены.

Строка 56:

Спасибо за чтение

appCompatImageView.perform(click());

Сегодня у меня была такая же ошибка, но в моем случае она была связана с управлением версиями библиотек. Я потратил много времени, пытаясь выяснить, как вернуть мои тесты, и одним из ключей к решению моей проблемы было установление для
