As of 1.1.6 this is the case. Is there a reason for this? It runs in dev mode. In ARTS I don't want to polute Rails internals in dev or production mode. Unfortunately I can't have passing tests _and_ keep a handle on my objects currently.
This is known, see the comments for http://dev.rubyonrails.org/ticket/5935 .
I guess Ulysses will get to it eventually.
