Re: Write unit test for a controller that uses AuthComponent in CakePHP 2.0.3

I have posted this question in StackOverflow and Jose Lorenzo answered
me this:

"The actual correct answer should be using mock objects instead of
actually login the user in manually:

$this->controller = $this->generate('Users', array(
'components' => array('Auth' => array('user')) //We mock the
Auth Component here
));
$this->controller->Auth->expects($this->once())->method('user') //
The method user()
->with('id') //Will be called with first param 'id'
->will($this->returnValue(2)) //And will return something for
me
$this->testAction('/users/edit/2', array('method' => 'get'));"

He is actually right but I'm still having problem when dealings with
models. For example, suppose I am testing an action that uses `save`
and `create` methods of a model. I tried to configure the expectations
like this:

$this->Users->User->expects($this->once())->with('save')->will($this-
>returnValue(true));
$this->testAction('/signup', array('data' => $data));

The action actually calls `save` to create a new User, but PHPUnit
says that it was never called. I have created `$this->Users`
controller in `ControllerTestCase::setUp()` like this:

$this->Users = $this->generate('Users', array(
'components' => array('Session', 'Auth' => array('user'))
'models' => 'User'
));

According to documentation, not passing any arguments to a mocked
models implies every method is stubbed. So what am I doing wrong here?

Thanks!
