Is that right? Or should that line automatically stub the AR methods like new, save, create, etc to prevent any DB activity but give the illusion of talking to the DB? The latter is is what I was thinking for the model specs, although the alert exception would also be a good idea- especially for the controllers, views, and helpers. I have yet to dive into the rspec internals but I would definitely like to contribute. Let me know if the alert idea is what you meant. Thanks, Ben
