Question

I am searching for a solution to get my test (which actually is an ActivityInstrumentationTextCase2) testing the onActivityResults method of my Activity with a special (mock) request- / resultcode and intent…

Code:
method should be tested:

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        switch (requestCode) {
        //In this case the user selected an image from his harddrive
        case StartupActivity.PICK_IMAGE:
            if (resultCode == Activity.RESULT_OK) {
                this.processSelectedFile(data.getData());
            }
            break;
        }
    }

test class:

public void testOnActivityResult() {
        //here I would like to call the onActivityResult method from my mActivity object.
    }

Answer 1

To test a protected member, declare (in your test project) a new class that derives from your target:

public class TestMyActivity : MyActivity
{

  //constructors

   public void testOnActivityResult(int requestCode, int resultCode, Intent data) { 
       //call super one
       super.onActivityResult(requestCode, resultCode, data);
   }

}

Now in your test, create one of these and you can call the method.
