I am doing the django tutorial and I don’t understand why this test is failing. I am unsure if this is the expected behavior from following the tutorial or if I messed something up along the way. I am expecting an empty list, but the lists differ.

‘latest\_question\_list’ is what I assigned to the context\_object\_name of my IndexView class, but from there I don’t know where to go.

We’ll need you to post your `tests.py` file here. (We may also end up needing to see your views file as well, but we’ll start with the tests.)

Thanks for looking at it. I compared the tutorial’s test with a diff tool, but I still might have missed something.

What you have:

> [@millennialboomer](#):
>
> ```auto
> def test_future_question(self):
> """
> Questions with a pub_date in the future aren't displayed on
> the index page.
> """
> create_question(question_text="Future question.", days=30)
> response = self.client.get(reverse('polls:index'))
> self.assertContains(response, "No polls are available.")
> self.assertQuerysetEqual(['latest_question_list'], [])
> 
> ```

What the tutorial has:

```auto
   def test_future_question(self):
        """
        Questions with a pub_date in the future aren't displayed on
        the index page.
        """
        create_question(question_text="Future question.", days=30)
        response = self.client.get(reverse('polls:index'))
        self.assertContains(response, "No polls are available.")
        self.assertQuerysetEqual(response.context['latest_question_list'], [])

```

Yes there is a difference between the two.

🤦‍♂️ Thanks. Looks like I just needed an extra pair of eyes. My tests are passing now.
