[rspec-users] Need help using URL helpers in controller tests

[Christopher Bailey]

I've moved on from this with a bit different approach.  But, I also found
that the "get" (or whichever http method used) call expects the first
parameter to be an action, so passing in a string that is a path or URL
doesn't work for that.
