我正在尝试使用测试支持库框架测试基本的未绑定服务:http: //developer.android.com/tools/testing-support-library/index.html

LocalService.java:

public class LocalService extends Service {
@Override
public IBinder onBind(Intent intent) {
        return null;
    }
}

LocalServiceTest.java:

@RunWith(AndroidJUnit4.class)
public class LocalServiceTest {
    @Rule
    public final ServiceTestRule mServiceRule = new ServiceTestRule();

    @Test
    public void testWithUnboundService() throws TimeoutException {
        Intent serviceIntent =
            new Intent(InstrumentationRegistry.getTargetContext(), LocalService.class);

        mServiceRule.startService(serviceIntent);
    }
}

当我尝试运行测试时,我得到以下TimeoutException:

java.util.concurrent.TimeoutException: Waited for 5 SECONDS, but service was never connected
