You have to update the test "Edit Configuration" and include the AndroidJUnitRunner as the instrumentation runner.
I found the solution in this video: https://youtu.be/TGU0B4qRlHY?t=9m36s
Adding what @loeschg suggest: Make sure you check the logcat logs to ensure something isn't causing issues (crash) before the test is even run. Bad code in the @BeforeClass block could resulted in the "Empty Test Suite" message in Android Studio despite having properly set the test runner.
