AttributeError: 'TestPoll' object has no attribute 'factory', django rest framework, tests

Question

I'm currently working through the django api book to learn django rest framework in a virtualenv. I'm using python=3.6, django=2.2.5 and djangorestframework=3.10.3. I'm on the Testing and Continous Integration chapter which is chapter-8. I'm trying to write the first test on there that is:

from rest_framework.test import APITestCase
from rest_framework.test import APIRequestFactory

from polls import apiviews

# Create your tests here.


class TestPoll(APITestCase):

    def setup(self):
        self.factory = APIRequestFactory()
        self.view = apiviews.PollViewSet.as_view({'get': 'list'})
        self.uri = '/polls/'

    def test_list(self):
        request = self.factory.get(self.uri)
        response = self.view(request)
        self.assertEqual(response.status_code, 200, 'Expected Response Code 200, received {0} instead'.format(response.status_code))

but whenever I run it using python manage.py test it returns with the following error:

Creating test database for alias 'default'...
System check identified no issues (0 silenced).

I can clearly see the factory attribute and how it's called/accessed. I've tried to access the request and response attributes using self but that has no effect. So what is the problem?
