response = render_reverse(mock_f(), mock_kwargs())
self.assertTrue('/natrium/cb/details/' in response)
But instead, I get
File "/var/lib/graphyte-webclient/graphyte-webenv/lib/python2.6/site-packages/django/core/urlresolvers.py", line 296, in reverse
"arguments '%s' not found." % (lookup_view_s, args, kwargs))
NoReverseMatch: Reverse for 'dummy_readfile' with arguments '('123',)' and keyword arguments '{}' not found.
Why is it calling reverse instead of my mock_reverse (it is looking up my urls.py!!)
The author of Mock library Michael Foord did a video cast here (around 9:17), and in the example he passed the mock object request to the view function index. Furthermore, he patched POll and assigned an expected return value.
Isn't that what I am doing here? I patched reverse?
Thanks.
