Django docs Polls App, Diferent queryset returns same object values but QuestionIndexViewTests works for one query and fails for other

In polls application I added annotation to check one to many relationship between Question and Choice models such that, Index only return questions with more than one choices to be displayed but my testcase fails all the time with annotation where both query returns same data.

views.py (Not Working: Added `annotate(num = Count('choice')).filter(num__gt=1))`
{{{
class IndexView(generic.ListView):
    template_name = 'polls/index.html'
    context_object_name = 'latest_question_list'

    def get_queryset(self):
        """Return the last five published questions."""
        return Question.objects.annotate(num = Count('choice')).filter(num__gt=1).filter(pub___lte=timezone.now()).order_by('-pub_date')[:5]
}}}
Error:
{{{
Traceback (most recent call last): File "C:\Users\hmnsh\repos\DjangoApp\mysite\polls\tests.py", line 80, in test_past_question ['']
File "C:\ProgramData\Anaconda3\envs\django\lib\site-packages\django\test\testcases.py", line 940, in assertQuerysetEqual return self.assertEqual(list(items), values, msg=msg) AssertionError: Lists differ: [] != ['']
}}}

Please help.
