Testing docs for Grails 2.0 @TestFor do not enumerate all provided instances mixed into test

As noted in the existing docs (section 9.1.1) @TestFor provides a new instance variable for testing:

-
Adding the TestFor annotation to a controller causes a new "controller" field to be automatically created for the controller under test.
-

In a similar way, a service class gets a "service" field, but that is not documented. Apparently, other @TestFor insertions likely apply and should enumerated.
