What is the correct way to test django with APIReqFactory or mock?

Question

I want to test with django, but they do not run and I do not understand, that I am wrong, the following error returns: line 44, in test_put res = self.view(req) Ran 5 tests in 0.009s FAILED (failures=2). Destroying test database for alias 'default'... Expected view ActorViewSet to be called with a URL keyword argument named "pk". Fix your URL conf, or set the .lookup_field attribute on the view correctly.

My testCase:

from rest_framework.test import APITestCase, APIRequestFactory

from .views import ActorViewSet

class TestActor(APITestCase):
    def setUp(self):
        self.factory = APIRequestFactory()
        self.view = ActorViewSet.as_view({'get': 'list',
                                      'get': 'retrieve',
                                      'post': 'create',
                                      'put': 'update',
                                      'delete': 'destroy'})
        self.url = '/actor/'

    def test_list(self):
        req = self.factory.get(self.url)
        res = self.view(req)
        self.assertEqual(res.status_code, 200,
                     'expected http code 200'
                     .format(res.status_code)
                     )

    def test_get_one(self):
        self.get_one_url = '/actor/1'
        req = self.factory.get(self.get_one_url, format='json')
        res = self.view(req)
        self.assertEqual(res.status_code, 200,
                     'expected http code 200'
                     .format(res.status_code)
                     )

    def test_create(self):
        data = {'movie_title': 'type', 'name': 'TCY', 'awards': 5}
        req = self.factory.post(self.url, data, format='json')
        res = self.view(req)
        self.assertEqual(res.status_code, 201,
                     'exepted created 201'
                     .format(res.status_code)
                     )

    def test_put(self):
        self.get_one_url = '/actor/1'
        data = {'movie_title': 'type', 'name': 'TCY', 'awards': 3}
        req = self.factory.put(self.get_one_url, data, format='json')
        res = self.view(req)
        self.assertEqual(res.status_code, 204,
                     'expected http code 204'
                     .format(res.status_code)
                     )

    def test_destroy(self):
        self.get_one_url = '/actor/1'
        data = {'movie_title': 'type', 'name': 'TCY', 'awards': 3}
        req = self.factory.delete(self.get_one_url, data, format='json')
        res = self.view(req)
        self.assertEqual(res.status_code, 204,
                     'expected http code 204'
                     .format(res.status_code)
                     )

I know this is a bit late, but since this was my first google hit I want to give the solution for others may having the same issue.

def test_put(self):
    self.get_one_url = '/actor/'
    data = {'movie_title': 'type', 'name': 'TCY', 'awards': 3}
    req = self.factory.put(self.get_one_url, data, format='json')
    res = self.view(req, pk=1)
    self.assertEqual(
        res.status_code, 204,
        'expected http code 204'.format(
            res.status_code
         ))

Hope that saves someone some time
