[rspec-users] How it would be tested?

Alright, as far as I know, the most common approach is to make up some
data for each controller spec, and one of the techniques for doing
this is fixtures (e.g. found in rails) -- another is the mocks, of
course.
Fixtures aren't exactly the hottest offer today, but to me, they are
probably the easiest choice for those messages of yours.

So, I suppose you may want to type in some message data in the
corresponding fixture file. (see
http://ar.rubyonrails.org/classes/Fixtures.html etc).
If you insist on mocking the messages, that would primarily go into
before :all block.

Then, in the blocks like 'it "should see all public messages"' you
make requests with the correctly mocked user and check the returned
messages versus the test data (you know which messages are supposed to
return).

Good luck,
Costa.
