Where to put test/mocks/development?

According to the Rails 2.1 changeset, creating mock objects for use in test and development environments is 'antiquated'.

If that's so, where should you put them?

I'm upgrading an app from 2.0.5 to 2.1.0 and we have mocked some objects which make external calls. The mocks for those objects live in 'test/mocks/development' and 'test/mocks/test'.

Where should they go, if not there?

I find that those directories don't get loaded when I use gem dependencies with "config.gem" in my environment.rb. If I remove the config.gem statements, they DO get loaded.

I'd love to use the dependencies, but how do I load my mocks?

Thanks, Isaac
