I've been searching around for ways to create a gem with RSpec, but haven't found descriptive tutorials.
I started out with Ryan Bates' Making a gem, but I'm looking for a tutorial that discusses creating an acts_as style gem with RSpec.
By acts_as, I mean to say that the gem adds certain methods to an existing class in Rails. Why is this important? Because I've found gem templates like New Gem, got a spec to run but when I try to test an Active Record object it starts choking. I've tried requiring active_record in spec_helper.rb but I must be doing something wrong because it doesn't solve the problem.
When it comes to plugins, I found this Rails Guide. If there's a gem version for that around that'd be awesome.
Thanks guys!
P.S. I love screencasts.
