[Trac-dev] trac + mock

[Jeffrey Ratcliffe]

I'm trying to use mock to test parts of my trac plug-in.

If I try something like:

def test_process_request(self):
""" Test the process_request method """

with patch('trac.web.api.Request', return_value=None) as mock_req:
mock_req.method = 'POST'
mock_req.args.base_path = 'mybasepath:port'
mock_req.args.project = 'proj'
mock_req.args.milestone = 'ms1'

with patch('trac.web.api.Request.redirect') as mock_redirect:
mock_redirect.return_value = '?project=proj&milestone=ms1'

self.assertEqual(MyPluginClass.process_request(ComponentManager(),
trac.web.api.Request(EnvironmentStub(), None)),
'mybasepath:port?project=proj&milestone=ms1',
'POST triggers redirect')

I get the error message:
TypeError: unbound method process_request() must be called with
MyPluginClass instance as first argument (got ComponentManager
instance instead)

If I change the assertion to:


self.assertEqual(MyPluginClass.process_request(MyPluginClass(),
trac.web.api.Request(EnvironmentStub(), None)),
'mybasepath:port?project=proj&milestone=ms1',
'POST triggers redirect')

I get:
AssertionError: First argument must be a ComponentManager instance

How can I do this?

Regards

You haven't instantiated an instance of MyPluginClass. Try:

env = EnvironmentStub()
my_plugin = MyPluginClass(env)

Also, you might want to use MockRequest (since 1.0.11):
