I tried starting a JUnit test (robotium) for my app:

public class MainTest extends ActivityInstrumentationTestCase2<MainActivity> {
    private Solo solo;

    public MainTest() {
        super("nix.android.contact", MainActivity.class);// TODO Auto-generated constructor stub
    }

    protected void setUp() throws Exception {
        super.setUp();
        solo = new Solo(getInstrumentation(), getActivity());
    }

    public void AddContact() {
        solo.assertCurrentActivity("main", MainActivity.class);
    }
}

Manifest

 <instrumentation
    android:name="android.test.InstrumentationTestRunner"
    android:targetPackage="nix.android.contact" />

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <uses-librar

y android:name="android.test.runner" />
    </application>

When I try to run the test this is the error I get in the console:

Test run failed: Test run failed to complete. Expected 1 tests, received 0

I tried creating another test a different app (very simple app) and it works.

I had the same issue while running instrumentation tests on Android (@RunWith(AndroidJUnit4.class)).

I had the following error:

Tests on Nexus_5X_API_26(AVD) - 8.0.0 failed: 
Test run failed to complete. Expected 156 tests, received 152

The problem was that one of the test classes was failing inside a method marked with @BeforeClass, hence no tests were executed for that particular class. Moreover that, the exception which was thrown inside @BeforeClass didn't end-up in the tests-output/report. That's why it was hard to find a reason of "Expected N tests, received M" error message.

So, if you run into the same issue - check your @Before and @BeforeClass implementations - an exception there could be the reason. Hope this helps.
