Best practice for common functional tests?

All,

I'm working on an ActiveScaffold based application, and in the interest
of getting more functional test coverage, I'd like to verify things
about AS-generated screens in the context of multiple controllers.

In order to share these tests, I've created methods in test_helper.rb,
and simply invoke them from a method in each of the controllers.

Does anyone have a good recommendation for a way to manage functional
tests that you want to run across multiple controllers without having to
place a test method that simply calls a common test in each functional
test file?

Thanks,
Wes
