Testing authentication in Django Rest Framework Views -- Cannot authenticate when testing

Question

After struggling mightily with this issue, I've come asking for a bit of help. I'm writing a test for a Django Rest Framework view, testing whether or not I can access the data whilst authenticated, and not. However, even when I'm authenticated, I still get 401 UNAUTHORIZED every time. Here's my tests:

from django.test import TestCase
from django.contrib.auth.models import User

from rest_framework.authtoken.models import Token
from rest_framework.test import APIRequestFactory, APIClient

from apps.core import models, admin
from apps.rest import views


class TestAPIViews(TestCase):
    def setUp(self):
        self.factory = APIRequestFactory()
        self.client = APIClient()
        self.user = User.objects.create_user('testuser', email='[email protected]', password='testing')
        self.user.save()
        token = Token.objects.create(user=self.user)
        token.save()

    def _require_login(self):
        self.client.login(username='testuser', password='testing')

    def test_ListAccounts_not_authenticated(self):
        request = self.factory.get('/accounts/')
        view = views.ListAccounts.as_view()
        response = view(request)
        self.assertEqual(response.status_code, 401,
            'Expected Response Code 401, received {0} instead.'.format(response.status_code))

    def test_ListAccounts_authenticated(self):
        self.client._require_login()
        print(self.user.is_authenticated()) # returns True
        request = self.factory.get('/accounts/')
        view = views.ListAccounts.as_view()
        response = view(request)
        self.assertEqual(response.status_code, 200,
            'Expected Response Code 200, received {0} instead.'.format(response.status_code))

And here is the code for my DRF View:

from django.shortcuts import render
from django.contrib.auth import authenticate, login, logout
from django.db.models import Q


from apps.core import serializers, models
from apps.rest.permissions import IsAccountOwner

from rest_framework.views import APIView
from rest_framework import status, authentication, generics
from rest_framework.response import Response
from rest_framework.authtoken.models import Token
from rest_framework.authentication import SessionAuthentication, TokenAuthentication
from rest_framework.permissions import IsAuthenticated
from rest_framework.response import Response

from apps.core import serializers, models

'''
Auth Mixin for Account Admin Access
'''
class AuthMixin:
    authentication_classes = (authentication.TokenAuthentication,
                              authentication.SessionAuthentication)
    permission_classes = (IsAuthenticated,)


class GenericList(AuthMixin, generics.ListAPIView):
    def get_queryset(self):
        # Stubbed out - doing nothing special right now
        qs = self.model.objects.filter()
        return qs


class ListAccounts(GenericList):
    model = models.Account
    serializer_class = serializers.AccountSerializer

As one can see, I'm calling login in the test_ListAccounts_authenticated, and then printing out whether or not I'm authenticated (Which returns True), but I get a 401 UNAUTHORIZED Error no matter what. Anything I'm missing? Thanks in advance.

Instead of calling self.factory.get(), call self.client.get().

I'm guessing self.client.login has no effect on self.factory.
