django test client trouble

Question

I've got a problem... we're writing project using django, and i'm trying to use django.test.client with nose test-framework for tests.

Our code is like this:

from simplejson import loads
from urlparse import urljoin

from django.test.client import Client

TEST_URL = "http://smakly.localhost:9090/"

def test_register():

    cln = Client()

    ref_data = {"email": "unique@mail.com", "name": "Василий", "website": "http://hot.bear.com", "xhr": "true"}

    print urljoin(TEST_URL, "/accounts/register/")
    response = loads(cln.post(urljoin(TEST_URL, "/accounts/register/"), ref_data))

    print response["message"]

and in nose output I catch:

Traceback (most recent call last):
  File "/home/psih/work/svn/smakly/eggs/nose-0.11.1-py2.6.egg/nose/case.py", line 183, in runTest
    self.test(*self.arg)
  File "/home/psih/work/svn/smakly/src/smakly.tests/smakly/tests/frontend/test_profile.py", line 25, in test_register

    response = self.request(**r)
  File "/home/psih/work/svn/smakly/parts/django/django/test/client.py", line 225, in request
    response = self.handler(environ)
  File "/home/psih/work/svn/smakly/parts/django/django/test/client.py", line 69, in __call__
    response = self.get_response(request)
  File "/home/psih/work/svn/smakly/parts/django/django/core/handlers/base.py", line 78, in get_response
    urlconf = getattr(request, "urlconf", settings.ROOT_URLCONF)
  File "/home/psih/work/svn/smakly/parts/django/django/utils/functional.py", line 273, in __getattr__
    return getattr(self._wrapped, name)
AttributeError: 'Settings' object has no attribute 'ROOT_URLCONF'

My settings.py file does have this attribute.

If I get the data from the server with standard urllib2.urllopen().read() it works in the proper way.

Any ideas how I can solve this case?
