factory_girl is a fixtures replacement with a straightforward definition syntax, support for multiple build strategies (saved instances, unsaved instances, attribute hashes, and stubbed objects), and support for multiple factories for the same class (user, admin_user, and so on), including factory inheritance.
factory_girl_rails provides Rails integration for factory_girl. All Rails-specific features are only compatible with Rails 3.
Currenty, automatic factory definition loading is the only Rails-specific feature.
