* Continue evolution toward ActiveSupport::TestCase and friends. #10679 [Josh Peek]

* TestCase: introduce declared setup and teardown callbacks. Pass a list of methods and an optional block to call before setup or after teardown. Setup callbacks are run in the order declared; teardown callbacks are run in reverse.  [Jeremy Kemper]
