Rails 3.1 and minitest

I'm looking for a simple way to integrate minitest/spec with Rails
3.1. Anybody have it working?

There's an older article on MetaSkills about this but it adds stuff I
don't want.

I'll bump this. I too am interested in getting minitest working
especially with autotest.

I kind of got something going but it's ugly and doesn't work with autotest.
