Mocking models provided in Rails plugins

Hey folks,

How do I mock a model that is given to me by a Rails plugin? I’m
trying to mock Session from the restful_authentication plugin but I
get a number of errors telling me RSpec doesn’t recognize Session.

NameError in ‘SessionsController handling GET /sessions/new should be
successful’
uninitialized constant Session

An example of my usage:

before do
@session = mock_model(Session)
Session.stub!(:new).and_return(@session)
end

Thanks!

Dan C.

class Session; end

You can stick that in spec_helper.rb if you use Session in a lot of
places.

I think you can also do Session.class_eval {} somewhere and that’ll
load up the actual Session class instead of the dummy implementation I
just showed. It won’t use the implementation in your specs of course,
but it loads the provided class into memory.

Your problem is that the class isn’t just Session, it’s
CGI::Session::ActiveRecordStore::Session

Dan, you can take a look at what *court3nay did, here:
