Creating Test-Specific URL Patterns and View Functions in Django

Until Django 1.9, it seems that the urls attribute was written in SimpleTestCase, but when reading the code:

def _urlconf_setup(self):
    if hasattr(self, 'urls'):
        warnings.warn(
            "SimpleTestCase.urls is deprecated and will be removed in "
            "Django 1.10. Use @override_settings(ROOT_URLCONF=...) "
            "in %s instead." % self.__class__.__name__,
            RemovedInDjango110Warning, stacklevel=2)
        set_urlconf(None)
        self._old_root_urlconf = settings.ROOT_URLCONF
        settings.ROOT_URLCONF = self.urls
        clear_url_caches()

Since it was written as deprecated, I followed this:

@override_settings(ROOT_URLCONF=...) 

and it worked.

from django.conf.urls import url
from django.core.urlresolvers import reverse
from django.http import JsonResponse
from django.test import TestCase, override_settings

from lib.current_request import get_current_request


def current_request_view(request):
    """
    View for checking the operation of current_request()
    """
    current_request = get_current_request()

    return JsonResponse({
        'current_request_path': current_request.path,
        'request_path': request.path,
    })


urlpatterns = [
    url(r'^current-request/$', current_request_view,
        name='current_request_view')
]


class CurrentRequestTest(TestCase):
    @override_settings(ROOT_URLCONF="lib.tests.test_current_request")
    def test_current_request(self):
        response = self.client.get(reverse('current_request_view'))
        data = response.json()
        self.assertEqual(data['current_request_path'], '/current-request/')
        self.assertEqual(data['request_path'], '/current-request/')
