Quelqu'un sait-il comment tester la configuration suivante à l'aide de Robolectric?
Fragment contenant un ViewPager, des données chargées avec un CursorLoader.
Avec le code ci-dessous, le CursorLoader n'est jamais poussé dans l'adaptateur pour le pager de vue. Je suis coincé à l' await()appel.
EventsFragmentTest.java:
@RunWith(CustomRobolectricTestRunner.class)
public class EventsFragmentTest extends AbstractDbAndUiDriver
{
// which element in the view pager we are testing
private static final int TEST_INDEX = 0;
protected SherlockFragmentActivity mActivity;
protected EventsFragment_ mFragment;
@Override
@Before
public void setUp() throws Exception
{
// create activity to hold the fragment
this.mActivity = CustomRobolectricTestRunner.getActivity();
// create and start the fragment
this.mFragment = new EventsFragment_();
}
@Test
public void sanityTest()
{
// create an event
final Event event = this.createEvent();
// create mock cursor loader
final Cursor cursor = this.createMockEventCursor(event);
this.mFragment.setCursorLoader(mock(CursorLoader.class));
when(this.mFragment.getCursorLoader().loadInBackground()).thenReturn(cursor);
CustomRobolectricTestRunner.startFragment(this.mActivity, this.mFragment);
await().atMost(5, SECONDS).until(this.isCursorLoaderLoaded(), equalTo(true));
// check for data displayed
final TextView title = this.getTextView(R.id.event_view_title);
final TextView text = this.getTextView(R.id.event_view_text);
// exists and visible is enough for now
this.getImageView(R.id.event_view_image);
assertThat(title.getText().toString(), equalTo(event.getTitle()));
assertThat(text.getText().toString(), is(event.getText()));
// clean up
cursor.close();
}
@Override
protected View getRootView()
{
return ((ViewPager) this.mFragment.getView().findViewById(R.id.events_pager)).getChildAt(TEST_INDEX);
}
private Callable<Boolean> isCursorLoaderLoaded()
{
return new Callable<Boolean>()
{
public Boolean call() throws Exception
{
return EventsFragmentTest.this.mFragment.isCursorLoaderLoaded(); // The condition that must be fulfilled
}
};
}
/**

*
* @return
*/
protected Event createEvent()
{
// create a random event
final Event event = new Event();
event.setImage(null);
event.setLink("/some/link/" + RandomUtils.getRandomString(5)); //$NON-NLS-1$
event.setResourceUri("/rest/uri/" + RandomUtils.getRandomDouble()); //$NON-NLS-1$
event.setText("this is a test object " + RandomUtils.getRandomString(5)); //$NON-NLS-1$
return event;
}
protected Cursor createMockEventCursor(final Event event)
{
// Create a mock cursor.
final Cursor cursor = new CursorWrapper(mock(MockCursor.class));
when(cursor.getCount()).thenReturn(1);
when(cursor.getString(cursor.getColumnIndexOrThrow(EventTable.COLUMN_TEXT))).thenReturn(event.getText());

// return created event
return cursor;
