无法从“ rest_framework.test”导入名称“ URLPatternsTestCase”

from django.conf.urls import include, url
from rest_framework.test import APITestCase, URLPatternsTestCase
from readEstateApi import views
from django.core.urlresolvers import reverse

class AccountTests(APITestCase, URLPatternsTestCase):
    urlpatterns = [url(r'^login/$', views.login, name='login'),]

    def test_create_account(self):
        url = reverse('login-list')
        response = self.client.get(url, format='json')
        self.assertEqual(response.status_code, status.HTTP_200_OK)
        self.assertEqual(len(response.data), 1)
