Ben test destek kitaplığı çerçevesine temel bağlanmamış hizmetini test etmeye çalışıyorum

Question

Android JUnit 4 instrumented testin içindeki ilişkisiz hizmetini başlatılamadı: 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 : Ben testi çalıştırmak çalıştığımda, TimeoutException aşağıdaki almak

@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); 
    } 
} 

:

Böyle bir hizmeti ServiceTestRule ile test etmek mümkün mü? Hayır ise, JUnit 4 test sınıflarını kullanarak hizmetleri başlatmak ve durdurmak için uygun başka bir yol var mı?

çalıştı;

Answer 2

Bu bu bir

@Rule kamu nihai ServiceTestRule mServiceRule = ServiceTestRule.withTimeout (60L, TimeUnit.SECONDS) deneyin bana

@Test(timeout=1000 * 60) 
public void testWithStartedService(){ 
    try { 
     mServiceRule.startService(
       new Intent(InstrumentationRegistry.getTargetContext(), UpdaterService.class)); 
    } catch (TimeoutException e) { 
     e.printStackTrace(); 
    } 
    //do something 
}
