RuntimeError: maximum recursion depth exceeded whi

Question

this error arises when i try to run the following test case which is written in models.py of my django app named 'administration' :

from django.test import Client, TestCase
from django.core import mail


class ClientTest( TestCase ):

    fixtures = [ 'testdata.json' ]

    def test_get_register( self ):
        response = self.client.get( '/accounts/register/', {} )
        self.assertEqual( response.status_code, 200 )

the error arises at this line specifically:

response = self.client.get( '/accounts/register/', {} ) 

my django version is 1.2.1 and python 2.6 and satchmo version is 0.9.2-pre hg-unknown. I code in windows platform(xp sp2). The command to run test case is:

python manage.py test administration

the complete error log is as follow:

Answer 1

django test client uses default base url:

http://testserver/

which makes your test url /accounts/register/ into:

http://testserver/accounts/register/

so you should add 'testserver' in django sites.site model as a base url. maximum recursion depth exceed because django client did'nt find 'testserver' as a domain in sites.site
