Best practice for common functional tests?


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
