otooh - having some scenarios logging in using a post and some by  
poking around under the hood creates an untested logical binding  
between the post and the poking. This has the same risk associated  
with it that raises so much concern about mocks without integration  
tests that don't use mocks.

I'm not saying that there should be a visible log-in step in every  
scenario. I would just use a request (or series of requests) instead  
of controller.send("current_user=",...).
