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

Question

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

public class MainTest extends ActivityInstrumentationTestCase2 {
    private Solo so         


        

Answer 1

All tests name should start with prefix "test".

Answer 2

I had this problem when I didn't have a no-args constructor.

public class MainActivityTest extends
    ActivityInstrumentationTestCase2<MainActivity_> {

public MainActivityTest() {
    super(MainActivity_.class);
}
