Remember, rSpec is Behavioural.  The code behind "restrict_to" doesn't
matter; it's the behaviour that matters.   As such, your view-spec
should only know about the code in that view.  So for example, there's
no mention of a "user" or "role" model there, only a "restrict_to"

Spec out the "restrict_to" code, rather than setting up a complex
chain of fragile model interactions.  This means that you can change
the whole ACL system, but as long as it conforms to the same
interface, restrict_to("rolename"), your specs will suceed.  You can
also change the associations or the name of your models, or add some
fancy caching, anything, and this particular spec won't die.

The fact that you're stubbing "find" calls in the *view* spec
indicates that you're probably testing things that are out of the
scope of that spec.

The actual ACL system should be tested on its own, not in the context of a view.
