Hi Andrea,
I don't think that it doesn't make it easier to test your actions if
you create a subclass of ActionTests as there are no utility methods in
there that could help you.
However if you really want to test your actions (I neglected these
somehow for most of the action functionality), I would create an
abstract subclass of TestCase where you implemented some utility
methods to make action-testing more convenient.
Hope this helps,
Lukas
