Почему Client() в django-test выдает ошибку на проверку страницы?

Сейчас проверяю страницы на "есть или нет" с помощью Client() в test.py django и не получается пройти ряд страничек, появляется ошибка.

test.py

from django.test import TestCase

class Dynamic_pages(TestCase):
    def test_video(self):
        response = self.client.get('/video6') # или просто response = self.client.get('/video' ')
        self.assertEqual(response.status_code, 200)

ulrs.py

url(r'^video(?P<video_id>[0-9]+)$', views.video, name='video'),

views.py

def video(request, video_id):
    videoitem = Video.objects.get(id=video_id)
    comview = Video_com.objects.filter(video_link_id=video_id)
    comviewcount = comview.count()
    form = Video_comForm(request.POST)

    videosidebar = Video.objects.all().order_by('?')
    arsenalbar = Arsenal.objects.all().order_by('?')[0:3]

    videorandom = []

    for ars in videosidebar:
        if videoitem.id != ars.id:
            videorandom.append(ars)
        else:
            pass

    videorandom = videorandom[:6]

    context = {
        "videoitem": videoitem,
        "videorandom": videorandom,
        "arsenalbar": arsenalbar,
        "comview": comview,
        "comviewcount": comviewcount,
        "form": form,
    }
    return render(request, 'faceset/videopage.html', context)

ошибка теста:
