Unit testing the Auth Component - cakephp

Question

I am using the following code to test the login action in UsersController
public function testLogin() {
$data = array('User' => array(
'username' => 'hello',
'password' => '411'
)
);
$this->Users = $this->generate('Users',array('components'=> array('Auth','Session')));
$this->Users->Auth->staticExpects($this->once())
->method('user')
->with('id');
$this->testAction('/users/login', array('data' => $data, 'method' => 'post'));
}
and the fixture is-
class UserFixture extends CakeTestFixture {
public $import = array('model' => 'User', 'records' => true, 'connection' => 'fixture');
}
adn action is-
public function login() {
if($this->request->is('post')) {
if($this->Auth->login()) {
$this->redirect($this->Auth->redirect());
} else {
return false;
$this->Session->setFlash(__('Wrong Username Or Password,Please Try Again'));
}
}
}
It always showing
Expectation failed for method name is equal to when invoked 1 time(s).
Method was expected to be called 1 times, actually called 0 times.
What is the problem?Cant find any solution,and the reason also.Please help.

I think your problem mocking the auth component is that in addition to including auth in your components array, you need to specify which methods of Auth to mock, and how to mock them.
The way I deal with AuthComponent in my tests is I create a superclass with a method: _generateMockWithAuthUserId which mocks the Auth component, among other things, the way I need.
I've pasted the code from my superclass below.
class AppControllerTest extends ControllerTestCase {
public function setUp() {
parent::setUp();
$this->User = ClassRegistry::init('User');
}
public function tearDown() {
unset($this->User);
parent::tearDown();
}
public function testPlaceholder(){
// This just here so we don't get "Failed - no tests found in class AppControllerTest"
$this->assertTrue(true);
}
protected function _generateMockWithAuthUserId($contollerName, $UserId){
$this->authUserId = $UserId;
$this->authUser = $this->User->findById($this->authUserId);
$this->controller = $this->generate($contollerName, array(
'methods' => array(
'_tryRememberMeLogin',
'_checkSignUpProgress'
),
'components' => array(
'Auth' => array(
'user',
'loggedIn',
),
'Security' => array(
'_validateCsrf',
),
'Session',
)
));
$this->controller->Auth
->expects($this->any())
->method('loggedIn')
->will($this->returnValue(true));
$this->controller->Auth
->staticExpects($this->any())
->method('user')
->will($this->returnCallback(array($this, 'authUserCallback')));
}
public function authUserCallback($param){
if(empty($param)){
return $this->authUser['User'];
} else {
return $this->authUser['User'][$param];
}
}
}
And then here's a example of a class that inherits from that superclass. Take note of where/how it calls _generateMockWithAuthUserId. Basically, doing that sets up a suitable controller with Auth mocked for the appropriate user id.
<?php
require_once dirname(__FILE__) . DS . 'AppControllerTest.php';
class EmployeeNotesControllerTestCase extends AppControllerTest {
public $fixtures = array(
// your fixtures go here
);
public function setUp() {
parent::setUp();
$this->EmployeeNote = ClassRegistry::init('EmployeeNote');
}
public function tearDown() {
unset($this->EmployeeNote);
parent::tearDown();
}
public function testSupervisorIndexCanNotSeeNotesOnSelf() {
$authUserId = 1;
$this->_generateMockWithAuthUserId('EmployeeNotes', $authUserId);
$this->controller->Session
->expects($this->once())
->method('setFlash');
$result = $this->testAction('supervisor/employee_notes/index/'.$authUserId, array('return' => 'vars', 'method' => 'get'));
$this->assertTrue(empty($result['employeeNotes']));
}
}
Hope that helps.

I have found a solution.it worked.
public function testLogin() {
$data = array('User' => array(
'username' => 'sasa',
'password' => '111'
)
);
$this->Users = $this->generate('Users', array());
$result = $this->testAction('/users/login', array('data' => $data, 'method' => 'post'));
$this->assertEquals($data['User']['username'],$this->Users->Session->read('Auth.User.username'));
$result = $this->testAction('/users/logout');
}
