The spec library in Minitest is great. I've been able to use it within Rails unit tests no problem. However, Rails functional test inherit from ActionController::TestCase which provides instance variables like @controller in it's setup.
Has anyone been using the Minitest::Spec lib for their Rails functional tests?
If not, I'm considering creating a small library to do just that. I'm not too keen on rspec, and shoulda is starting to shift it's focus to rspec. It would be nice to have something lightweight and built on tools already provided.
