Great stuff, change looks perfect.

Could you also add an action named 'actions' to one of the TestApp 
controllers in the test suite, so that there is a regression test and 
evidence in the log/tests of _why_ this got changed?

This should be fairly trivial, as adding just an empty method should 
cause everything to explode, right?
