Koujou is a fixture replacement that requires no effort to use. You don't have to define a single thing in your test_helper or whatever. Just call the koujou method on your active record model, and you're off. Check out: http://www.michaelleung.us/koujou for all the juicy details. Please note this is a very early release of koujou, so if you find any issues, just post them here: http://github.com/mleung/koujou/issues
