परीक्षण onActivityResult()

Question

मैं निम्नलिखित गतिविधि है

package codeguru.startactivityforresult; 

import android.app.Activity; 
import android.content.Intent; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.Button; 
import android.widget.Toast; 

public class StartActivityForResult extends Activity { 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     this.startButton = (Button) this.findViewById(R.id.start_button); 
     this.startButton.setOnClickListener(onStart); 
    } 

    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     int result = data.getIntExtra(StartActivityForResult.this.getString(R.string.result), -1); 
     String msg = "requestCode=" + requestCode + ", resultCode=" + resultCode + ", result=" + result; 
     Toast.makeText(this, msg, Toast.LENGTH_LONG).show(); 
    } 

    private View.OnClickListener onStart = new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      Intent intent = new Intent(StartActivityForResult.this, ChildActivity.class); 

      StartActivityForResult.this.startActivityForResult(intent, R.id.child_request); 
     } 
    }; 
    private Button startButton = null; 
} 

और निम्नलिखित JUnit परीक्षण:

package codeguru.startactivityforresult; 

import android.app.Activity; 
import android.app.Instrumentation; 
import android.test.ActivityInstrumentationTestCase2; 
import android.test.UiThreadTest; 
import android.widget.Button; 
import junit.framework.Assert; 

public class StartActivityForResultTest extends ActivityInstrumentationTestCase2<StartActivityForResult> { 

    public StartActivityForResultTest() { 
     super(StartActivityForResult.class); 
    } 

    @Override 
    public void setUp() throws Exception { 
     super.setUp(); 

     this.setActivityInitialTouchMode(false); 

     this.activity = this.getActivity(); 
     this.startButton = (Button) this.activity.findViewById(R.id.start_button); 
    } 

    @Override 
    public void tearDown() throws Exception { 
     this.activity.finish(); 

     super.tearDown(); 
    } 

    @UiThreadTest 
    public void testStartButtonOnClick() { 
     Assert.assertTrue(this.startButton.performClick()); 

     Instrumentation.ActivityResult result = new Instrumentation.ActivityResult(Activity.RESULT_OK, null); 
     Assert.assertNotNull(result); 

     Instrumentation.ActivityMonitor am = new Instrumentation.ActivityMonitor(ChildActivity.class.getName(), result, true); 
     Assert.assertNotNull(am); 

     Activity childActivity = this.getInstrumentation().waitForMonitorWithTimeout(am, TIME_OUT); 
     Assert.assertNotNull(childActivity); 

     Assert.fail("How do I check that StartActivityForResult correctly handles the returned result?"); 
    } 
    private Activity activity = null; 
    private Button startButton = null; 
    private static final int TIME_OUT = 5 * 1000; // 5 seconds 
} 

आप देख सकते हैं, मैं कैसे पता लगा Instrumentation.ActivityResult का उपयोग कर एक परिणाम के नकली करने के लिए और Instrumentation.ActivityMonitor। मैं कैसे जांच कर लें कि StartActivityForResult.onActivityResult() ठीक से इस परिणाम हैंडल करते हैं?

Answer 1

उपयोग उद्देश्य ढांचे गतिविधि परिणाम

intending(hasComponent(DummyActivity.class.getName())).respondWith(new ActivityResult(resultCode, dataIntent)); 
rule.getActivity().startActivityForResult(new Intent(context,DummyActivity.class)); 

गतिविधि परिणाम तर्क पर यह सत्यापित उपहास करने के लिए

Answer 3

परीक्षण onActivityResult के लिए() अपने परीक्षण कक्षा में, तुम सब करने की जरूरत है:

1. एक ActivityMonitor जो ChildActivity निर्माण को पकड़ने और नकली retuning बनाएं ActivityResult।
2. बटन क्लिक जो परिणाम के लिए ChildActivity शुरू अनुकरण।
3. स्थिति और नकली ActivityResult पर कुछ दावे करते हैं।

नमूना StartActivityForResult:

public class StartActivityForResult extends Activity { 
    private boolean activityResultIsReturned = false; 
    private String activityResult = null; 

    ... ... 

    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    activityResultIsReturned = true; 
    activityResult = data.getStringExtra("result"); 

    ... ... 
    } 

    ... ... 
} 

नमूना StartActivityForResultTest:

public class StartActivityForResultTest extends ActivityInstrumentationTestCase2<StartActivityForResult> { 
    ... ... 

    public void testOnActivityResult() { 
    // Get current Activity and check initial status: 
    StartActivityForResult myActivity = getActivity(); 
    assertFalse(myActivity.getActivityResultIsReturned()); 
    assertNull(myActivity.getActiityResult()); 

    // Mock up an ActivityResult: 
    Intent returnIntent = new Intent(); 
    returnIntent.putExtra("result", "This is the result"); 
    Instrumentation.ActivityResult activityResult = new Instrumentation.ActivityResult(Activity.RESULT_OK, returnIntent); 

    // Create an ActivityMonitor that catch ChildActivity and return mock ActivityResult: 
    Instrumentation.ActivityMonitor activityMonitor = getInstrumentation().addMonitor(ChildActivity.class.getName(), activityResult , true); 

    // Simulate a button click that start ChildActivity for result: 
    final Button button = (Button) myActivity.findViewById(com.company.R.id.open_next_activity); 
    myActivity.runOnUiThread(new Runnable() { 
     @Override 
     public void run() { 
     // click button and open next activity. 
     button.performClick(); 
     } 
    }); 

    // Wait for the ActivityMonitor to be hit, Instrumentation will then return the mock ActivityResult: 
    ChildActivity childActivity = getInstrumentation().waitForMonitorWithTimeout(activityMonitor, 5); 

    // How do I check that StartActivityForResult correctly handles the returned result? 
    assertTrue(myActivity.getActivityResultIsReturned()); 
    assertEqual(myActivity.getActiityResult(), "This is the result"); 
    } 

    ... ... 
}
