Django CMS 测试 - 找不到命名空间

Question

我在使用Django CMS进行测试时遇到了一个很奇怪的问题。当我运行命令：./manage.py test --settings=my_project.test_settings时，出现了以下错误：

错误：test_guest_list_view (apps.news.tests.test_views.NewsListViewTest) 测试访客是否看不到被禁用的条目 ---------------------------------------------------------------------- 回溯（最近的调用最后）：文件 "/home/robert/work/projects/my_project/apps/news/tests/test_views.py", 第52行，在test_guest_list_view response = self.client.get(self._get_list_url()) 文件 "/home/robert/work/projects/my_project/apps/news/tests/test_views.py", 第17行，在_get_list_url return reverse("news:list") 文件 "/home/robert/.virtualenvs/my_project/local/lib/python2.7/site-packages/django/core/urlresolvers.py", 第532行，在reverse key) NoReverseMatch: u'news' 不是一个注册的命名空间

但是当我只对那个应用运行测试时，一切都正常 - 所有测试都通过了。

这是我目前非常简单的测试类：

# -*- coding: utf-8 -*-
from django.contrib.auth.models import Permission
from django.contrib.contenttypes.models import ContentType
from django.core.urlresolvers import reverse
from django.test.utils import override_settings

from cms.test_utils.testcases import CMSTestCase

from apps.accounts.tests.factories import CustomUserFactory
from .factories import NewsFactory
from ..models import News


class BaseNewsTestCase(CMSTestCase):
    def _get_list_url(self):
        """Returns URL to objects list"""
        return reverse("news:list")

    def _create_data_structure(self):
        """Created test data"""
        # add objects
        self.disabled = NewsFactory(is_visible=False)
        self.enabled = NewsFactory()
        NewsFactory()
        NewsFactory()

        self.user = CustomUserFactory(username='user', password='user')

        # privileged_user
        self.privileged_user = CustomUserFactory(username='p_user',
                                                 password='p_user')

        # add permissions
        content_type = ContentType.objects.get_for_model(News)
        permissions_list = ('add_news', 'change_news', 'delete_news')
        permissions = Permission.objects.filter(content_type=content_type,
                                                codename__in=permissions_list)

        self.privileged_user.user_permissions.add(*permissions)


@override_settings(ROOT_URLCONF='apps.news.tests.urls')
class NewsListViewTest(BaseNewsTestCase):
    def test_guest_list_view(self):
        """Tests if guest can't see disabled entries"""
        self._create_data_structure()

        response = self.client.get(self._get_list_url())
        objects = response.context['object_list']

        self.assertEqual(len(objects), 3)
        for obj in objects:
            self.assertNotEqual(obj, self.disabled)

还有测试的URL：

# -*- coding: utf-8 -*-
from django.contrib import admin
from django.conf.urls import url, patterns, include

urlpatterns = patterns(
    '',
    url(r'^admin/', include(admin.site.urls)),
    url(r'^news/', include('apps.news.urls', namespace='news')),
    url(r'', include('cms.urls')),
)

有没有人知道是什么导致了这个问题？我按照这个链接来测试我的CMA应用钩子（http://django-cms.readthedocs.org/en/latest/extending_cms/testing.html）

我在这个项目的不同应用中有相同的测试模式，但没有出现这个错误。

django cms testing noreversematch urlresolvers test_case application_namespace guest_access
