• ab18b86 Inside tests: Using User.is_authenticated() and User.is_anonymous() as methods rather than properties is no longer supported. source:

  ERROR: test_view_site_2 (tests.test_views.ViewTest)
  Traceback (most recent call last):
    File "/Users/me/work/python/django-robots/tests/test_views.py", line 82, in test_view_site_2
      request = self.get_request(path='/', user=AnonymousUser(), lang='en')
    File "/Users/me/work/python/django-robots/tests/base.py", line 31, in get_request
      if user.is_authenticated():
  TypeError: 'bool' object is not callable
  

  It should be valid to use it as a property in Django 1.10+ source
