CakePHP 2.1 - Unit Testing Controllers $this->view and $this->contents equals null

Switching a over to cakephp 2.1 and just starting to learn unit
testing...

When I `ArticlesControllerTestCase::testView()`

and run

$this->testAction('articles/view/1');
debug($this->view);
debug($this->contents);
die;

both `$this->view and $this->contents` is equal to null

I've emptied the beforeFilter calls and beforeRender calls to try and
eliminate that...

I noticed that in the controller action, if I set `$this-
>render('view');` at the end of the method I get `$this->view` = 'what
it is suppose to be', but `$this->contents` = 'to the same thing and
does not contain the layout

any idea why this would be happening?
