Am I mocking this helper function right in my Django test?
- by CppLearner
lib.py
from django.core.urlresolvers import reverse
def render_reverse(f, kwargs):
"""
kwargs is a dictionary, usually of the form {'args': [cbid]}
"""
return reverse(f, **kwargs)
tests.py
from lib import render_reverse, print_ls
class LibTest(unittest.TestCase):
def test_render_reverse_is_correct(self):
#with patch('webclient.apps.codebundles.lib.reverse') as mock_reverse:
with patch('django.core.urlresolvers.reverse') as mock_reverse:
from lib import render_reverse
mock_f = MagicMock(name='f', return_value='dummy_views')
mock_kwargs = MagicMock(name='kwargs',return_value={'args':['123']})
mock_reverse.return_value = '/natrium/cb/details/123'
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.
