Adakah yang tahu cara menguji penyiapan berikut menggunakan Robolectric?
Fragmen berisi ViewPager, data dimuat dengan CursorLoader.
Dengan kode di bawah ini, CursorLoader tidak pernah didorong ke adaptor untuk halaman tampilan. Saya terjebak di await()telepon.
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());
when(cursor.getString(cursor.getColumnIndexOrThrow(EventTable.COLUMN_TITLE))).thenReturn(event.getTitle());
when(cursor.getString(cursor.getColumnIndexOrThrow(EventTable.COLUMN_IMAGE))).thenReturn(event.getImage());
when(cursor.getString(cursor.getColumnIndexOrThrow(EventTable.COLUMN_LINK))).thenReturn(event.getLink());

event.getResourceUri());
// return created event
return cursor;
}
}
