How can I correctly pass arguments to classbasedviews testing the Django REST Framework?

I want to test some views in the Django REST Framework (DRF) project.

The problem comes when I try to check views that have arguments in the URLs.

File urls.py

url(r'^(?Pcompany_hash>[\d\w]+)/(?Ptimestamp>[\.\d]*)/employees/$',
    EmployeeList.as_view(), name='employeelist'),

("<" in URLs has been deleted on purpose. Just it isn’t considered a tag and thus is not shown)

File views.py

class EmployeeList(ListCreateAPIView):
    serializer_class = EmployeeDirectorySerializer

    def inner_company(self):
        company_hash = self.kwargs['company_hash']
        return get_company(company_hash)

    def get_queryset(self):
        return Employee.objects.filter(company=self.inner_company())

File test.py

class ApiTests(APITestCase):
    def setUp(self):
        self.factory = APIRequestFactory()
        self.staff = mommy.make('directory.Employee', user__is_staff=True)
        self.employee = mommy.make('directory.Employee')

        self.hash = self.employee.company.company_hash

    def getResponse(self, url, myView, kwargs):
        view = myView.as_view()
        request = self.factory.get(url, kwargs)

        force_authenticate(request, user=user)

        response = view(request)
        return response

    def test_EmployeeList(self):
        kwargs = {'timestamp': 0, 'company_hash': self.hash}
        url = reverse('employeelist', kwargs=kwargs)
        testedView = EmployeeList

        response = self.getResponse(url, testedView,
                kwargs=kwargs)
        self.assertEqual(response.status_code, 200)

I'm getting this error:

company_hash = self.kwargs['company_hash']
KeyError: 'company_hash'

That is, the args aren't been passed to the view.

I've tried in so many different ways to pass by the args, but I can't find a solution.

I just found the problem!!

I was using APIRequestFactory() and should have been using the build in client factory from the APITestCase test class from Django REST Framework.
