Test DatePickerDialog with robolectric

[Łukasz Bandzarewicz]

Original question can be found on http://stackoverflow.com/questions/16652414/test-datepickerdialog-with-robolectric

I'm trying to write simple test for the DatePickerDialog:

@Test
public void shouldSetStartedOnDate() {
  activity.findViewById(R.id.cruise_form_pick_started_on_button).performClick();

  DatePickerDialog dialog = (DatePickerDialog) ShadowDatePickerDialog.getLatestDialog();
  assertThat(dialog.isShowing(), is(true));
  dialog.updateDate(2013, 3, 13);

  ShadowDialog shadowDialog = Robolectric.shadowOf(dialog);
  shadowDialog.clickOnText("Done");
  assertThat(dialog.isShowing(), is(false));

  TextView startedOnText = (TextView) activity.findViewById(R.id.cruise_form_started_on);
  assertThat(startedOnText.getText().toString(), equalTo("2013-03-13"));
}

Unfortunately during test execution dialog.updateDate(2013, 3, 13); raises null pointer exception.

In the debugger I noticed that dialog.mDatePicker instance variable is null.

How to test this dialog with robolectric? 

Where can I find good examples for date pickers?

I'm also having the same problem, as posted here: https://groups.google.com/forum/#!topic/robolectric/2pV0qFQcZZw
