Hi John

While not an answer to your question, you might like this post "Why I don’t use spork" as an alternative perspective. Kevin's argument is that "Spork solves the wrong problem".

After Nikolay taught me that you can have multiple RSpec guards in a Guardfile, having a Rails-independent lib with continuous development testing seems pretty feasible. (I haven't tried it, but I'm tangentially involved in a project where we may be able to give it a go.)

BTW there's also the Destroy All Software screencast "Fast Tests With and Without Rails"[2] which I found yesterday, sounds to describe the same idea. I haven't watched it yet though (maybe somebody else here has?) - $9 is a lot of money to spend on a whim you know :)

HTH in some way
