I'm trying to add a basic espresso test in my android application. My test file (located in androidTest/java folder) was generated by the 'record espresso test' feature and is as below :

package info.my_xxxx.activities;


import android.support.test.espresso.ViewInteraction;
import android.support.test.rule.ActivityTestRule;
import android.support.test.runner.AndroidJUnit4;
import android.test.suitebuilder.annotation.LargeTest;
import android.view.View;
import android.view.ViewGroup;
import android.view.ViewParent;

import org.hamcrest.Description;
import org.hamcrest.Matcher;
import org.hamcrest.TypeSafeMatcher;
import org.junit.Rule;
import org.junit.Test;
import org.junit.runner.RunWith;

import info.my_xxxx.R;

import static android.support.test.espresso.Espresso.onView;
import static android.support.test.espresso.action.ViewActions.click;
import static android.support.test.espresso.assertion.ViewAssertions.matches;
import static android.support.test.espresso.matcher.ViewMatchers.isDisplayed;
import static android.support.test.espresso.matcher.ViewMatchers.withId;
import static android.support.test.espresso.matcher.ViewMatchers.withText;
import static org.hamcrest.Matchers.allOf;

@LargeTest
@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:
        // https://google.github.io/android-testing-support-library/docs/espresso/idling-resource/index.html
        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(
                                                withId(android.R.id.content),
                                                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));
            }
        };
    }
}

As you can see, it's just about clicking on a view and checking if a view is existing or not... My gradle file (module level) is:

buildscript {

        maven { url 'https://maven.fabric.io/public' }

    }

}

All the dependencies seems to be ok but when running the test from android studio, I got this message after few minutes :

Tests ran to completion.

Line 56 is :

appCompatImageView.perform(click());

How you integrate Espresso in your project . I used its dependence like you but it didn't define .Ahmed

I had the same error today, but in my case, it was related to the libs versioning. I wasted a long time trying to figure out how to get my tests back passing, and one of the key for figuring my problem out was by setting the buildToolsVersion, compileSdkVersion and support-annotations lib to the same version.

So, please could you try to update your buildToolsVersion '25.2.0' and check if it works?
