CakePHP unittest mocked Auth component - unit-testing

Question

Code
class AclRowLevelsController extends AppController {
public $components = array(
// Don't use same name as Model
'_AclRowLevel' => array('className' => 'AclRowLevel')
);
public function view() {
$this->_AclRowLevel->checkUser();
...
}
}
class AclRowLevelComponent extends Component {
public function initialize(Controller $controller) {
$this->controller = $controller;
$this->AclRowLevel = ClassRegistry::init('AclRowLevel');
}
public function checkUser($permission, $model) {
$row = $this->AclRowLevel->find('first', array(
'conditions' => array(
'model' => $model['model'],
'model_id' => $model['model_id'],
'user_id' => $this->controller->Auth->user('id')
)
));
}
}
class AclRowLevelsControllerTest extends ControllerTestCase {
public function testViewAccessAsManager() {
$AclRowLevels = $this->generate('AclRowLevels', array(
'components' => array(
'Auth' => array(
'user'
),
'Session',
)
));
$AclRowLevels->Auth
->staticExpects($this->any())
->method('user')
->with('id')
->will($this->returnValue(1));
$this->testAction('/acl_row_levels/view/Task/1');
}
Problem
The query in the AclRowLevel component requires the Auth user id. I want to simulate user_id value '1' for the unit test.
The mocked Auth method 'user' in my test is not working for the call from the component. So the user id in that query has value null.
How should this be done?

Answer 1

Do a debug($AclRowLevels->Auth); to check if it really was mocked. It should be a mock object. If it is not for some reason try:
$AclRowLevels->Auth = $this->getMock(/*...*/);
The code inside checkUser() should go into the model by the way. Also I doubt this has to be a component at all. This seems to be used for authorization, so why not making it a proper authorization adapter?

Answer 2

This is what I was looking for:
$AclRowLevels->Auth
->staticExpects($this->any())
->method('user')
->will($this->returnCallback(
function($arg) {
if ($arg === 'id') {
return 1;
}
return null;
}
));
