	my $controller = MyApp::Controller::Root->new;

	$session{moose} = "ulf";
	
	$controller->private_action( $c );

	is( $stash{greeting}, "hello ulf" );

This approach is either a blessing or a curse depending on many
factors. Some best practices:

	rely on a well defined style in your code to ease mocking - if
	you use request/response you don't need to alias req/res.

	make sure you test small things - for example, don't test the
	forward to the view - this is a broad test that will probably
	need much more extensive mocking. This helps you remember to
	keep your actions small, too.

	Don't rely on this too much - maybe Selinium or
	Test::WWW::Mechanize::Catalyst for bigger "behavioral" tests
	that reallyh excercise full link paths are better.

Good luck!
