django自定义时区中间件导致django.contrib.humanize测试失败

Question

下面的自定义中间件处于活动状态时，会在我运行python manage.py test时导致此测试失败。我们运行的是Django 1.5.4：

FAIL: test_naturalday_uses_localtime    (django.contrib.humanize.tests.HumanizeTests)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/home/vagrant/.virtualenvs/endaga-server/local/lib/python2.7/site-packages/django/contrib/humanize/tests.py", line 161, in test_naturalday_uses_localtime
    self.humanize_tester([dt], ['yesterday'], 'naturalday')
  File "/home/vagrant/.virtualenvs/endaga-server/local/lib/python2.7/site-packages/django/contrib/humanize/tests.py", line 47, in humanize_tester
    msg="%s test failed, produced '%s', should've produced '%s'" % (method, rendered, result))
AssertionError: naturalday test failed, produced 'today', should've produced 'yesterday'

有问题的中间件：

class TimezoneMiddleware(object):
    """Activates django's timezone processing."""

    def process_request(self, request):
        """Intercedes during a request."""
        if not request.user:
            return
        try:
            user_profile = models.UserProfile.objects.get(user=request.user.id)
            timezone.activate(pytz.timezone(user_profile.timezone))
        except models.UserProfile.DoesNotExist:
            return

如何修改此中间件以使测试不会失败？

您可以在测试期间模拟它，或者确保用户时区与您运行测试的时区相同。
