Clearing class instance variables in between Rspec examples

I'm writing specs for a gem of mine that extends ActiveRecord. One of the things it has to do is set a class instance variable like so:

class MyModel < ActiveRecord::Base
  @foo = "asd"
end

Right now when I set @foo in one it "should" {} it persists to the next one. I understand this is normal Ruby behavior but I thought RSpec had some magic that cleaned everything out in between specs. I'd like to know how I can re-use a single AR model for all my tests (since creating a bunch of tables would be a pain) while being sure that @foo is being cleared between each test. Do I need to do this manually?

I wound up generating a method in my helper class that generated new classes with Class.new, so I could be sure that nothing was being left over in between tests.

You should simply make good use of the after :each block.

after(:each) do 
  @foo = nil
end
