I realise this probably won't help you directly because you state that you're not using shoulda but I had a similar problem with mocha stubs bleeding from one Shoulda test to another.
I found that reversing the order of the config.gem lines in environment.rb, thus: config.gem "thoughtbot-shoulda", :lib => "shoulda" #- shoulda must be loaded before mocha config.gem "mocha" #--or any_instance bleeds between tests resolved the problem. I didn't investigate why. Also, this problem didn't seem to occur when I ran under autotest. It only popped up when running the tests with rake. I expect because autotest runs the tests as separate processes. Good luck Ritchie -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
