AsyncTask onPostExecute() यूनिट टेस्ट केस

Question

में नहीं बुलाया मैं इस से संबंधित पोस्ट का एक समूह को देखा है, लेकिन कोई भी एक ही मुद्दा रहा हो रही है लगता है। GetBusinessRulesTask AsyncTask को बढ़ाता है। onPostExecute() कभी नहीं कहा जाता हो जाता है जब मैं एक इकाई परीक्षण मामले में इस पर अमल। हालांकि, अगर मैं वास्तविक ग्राहक कोड तो का उपयोग onPostExecute() हर कहा जाता है। यकीन नहीं है कि मैं यहाँ क्या गलत कर रहा हूँ।

टेस्ट मामला:

package com.x.android.test.api; 

import java.util.concurrent.CountDownLatch; 

import android.test.ActivityInstrumentationTestCase2; 
import android.test.UiThreadTest; 
import android.widget.Button; 

import com.x.android.api.domain.businessrule.BusinessRules; 
import com.x.android.api.exception.NetworkConnectionException; 
import com.x.android.api.tasks.GetBusinessRulesTask; 
import com.x.android.test.activity.SimpleActivity; 

public class GetBusinessRulesTaskTest 
    extends 
     ActivityInstrumentationTestCase2<SimpleActivity> { 
SimpleActivity mActivity; 
Button mButton; 

public GetBusinessRulesTaskTest() { 
    super("com.x.android.test.activity", SimpleActivity.class); 
} 

@Override 
protected void setUp() throws Exception { 
    super.setUp(); 
    mActivity = this.getActivity(); 
    mButton = (Button) mActivity 
      .findViewById(com.x.android.test.activity.R.id.b1); 
} 

public void testPreconditions() { 
    assertNotNull(mButton); 
} 

@UiThreadTest 
public void testCallBack() throws Throwable { 
    final CountDownLatch signal = new CountDownLatch(1); 
    final GetBusinessRulesTask task = (GetBusinessRulesTask) new GetBusinessRulesTask(
      new GetBusinessRulesTask.Receiver<BusinessRules>() { 
       @Override 
       public void onReceiveResult(BusinessRules rules, Exception e) { 
        assertNotNull(rules); 
        assertNull(e); 
        signal.countDown();// notify the count down latch 
       } 
      }); 
    task.start(mActivity.getApplicationContext()); 
    try { 
     signal.await();// wait for callback 
    } catch (InterruptedException e1) { 
     fail(); 
     e1.printStackTrace(); 
    } 
} 
} 

OnPostExecute:

@Override 
protected void onPostExecute(AsyncTaskResponse<O> response) { 
    Log.d(TAG, "onPostExecuted"); 
    if (mReceiver != null) { 
     mReceiver.onReceiveResult(response.getResponse(), response.getException()); 
    } 
} 

DoInBackground:

@Override 
protected AsyncTaskResponse<O> doInBackground(I... params) { 
    Log.d(TAG, "doInBackgroundr"); 
    try { 
     Uri uri = createUri(params); 
     mBaseRequest = new GetLegacyRequest(uri); 
     String json = mBaseRequest.executeRequest(); 
     O response = deserializeJson(json); 
     Log.d(TAG, "Returning AsyncTaskResponse"); 
     return new AsyncTaskResponse<O>(response, null); 
    } catch (Exception e) { 
     Log.e(TAG, "Error", e); 
     /* 
     AsyncTaskResponse<O> maintenance = ReadBusinessControlledPropertiesTask.blockingCall(mServiceLocatorUrl); 
     if(maintenance.getException() == null) { 
      MaintenanceException mExcep = new MaintenanceException(maintenance.getResponse()); 
      if (mExcep.isUnderMaintenance()) 
       return new AsyncTaskResponse(null,mExcep); 
     }*/ 
     return new AsyncTaskResponse<O>(null, e); 
    } 
} 

प्रारंभ विधि()

public AsyncTask<Void, Void, AsyncTaskResponse<BusinessRules>> start(
     Context context) throws NetworkConnectionException { 
    super.start(context); 
    Log.d(TAG, "start"); 
    return execute(); 
} 

समस्या मिली। अपने AsyncTask फ़ाइनल को न बनाएं और इसे चलाने योग्य के अंदर रखें।

ठीक:

public void testCallBack() throws Throwable { 
    final CountDownLatch signal = new CountDownLatch(1); 
    // Execute the async task on the UI thread! THIS IS KEY! 
    runTestOnUiThread(new Runnable() { 
    @Override 
     public void run() { 
      try { 
       GetBusinessRulesTask task = (GetBusinessRulesTask)new GetBusinessRulesTask(new GetBusinessRulesTask.Receiver<BusinessRules>() { 
          @Override 
          public void onReceiveResult(
            BusinessRules rules, Exception e) { 
           assertNotNull(rules); 
           assertNull(e); 
           signal.countDown();// notify the count downlatch 
          } 
         }); 
       task.start(mActivity.getApplicationContext()); 
      } catch (Exception e) { 
       Log.e(TAG, "ERROR", e); 
       fail(); 
      } 
     } 
    }); 
    try { 
     signal.await();// wait for callback 
    } catch (InterruptedException e1) { 
     fail(); 
     e1.printStackTrace(); 
    } 
}
