In your example User does not receive the #paginate call, the return
value of #accessible_by does. It looks like you're having both of
those methods return @users in your spec by default. Try updating your
spec to say...
@users.should_receive(:paginate)...
instead of
User.should_receive(:paginate)...

In case you can change your controller... this controller action seems
pretty vanilla. I would probably add some good model-level specs
around #accessible_by, and then have a few cucumber scenarios ensure
whatever it was that pulled up this page was working (I like scenarios
for pagination as well). To make things easier I would assign the
default PER_PAGE to a configuration setting or a constant so it can be
easily changed in a scenario. This can reduce scenario running time
and necessary setup whilst still ensuring behaviour.
Just an idea with the very little I know from what you pasted,
