[TYPO3-mvc] Re: HowTo write UnitTest for Controller?

[Heinz Schilling]

One step further I make this Controller Test class with some explanation I found on internet. This example doesn't work yet.

<?php
namespace <Vendor>\<Extension>\Tests;
/**
 * Test case for class ClientController.
 *
 * @package <Vendor>
 * @subpackage Ereport
 */
class ClientControllerTest extends \TYPO3\CMS\Extbase\Tests\Unit\BaseTestCase {

    /**
     * @var \<Vendor>\<Extension>\Controller\ClientController
     */
    protected $accessibleFixture;

    /**
     * @var \<Vendor>\<Extension>\Domain\Repository\ClientRepository
     */
    protected $mockClientRepository;

    /**
     * Set up
     */
    public function setUp() {
        // Mock of the controller
        //
        // Some variables like $view are protected in the controller classes of extbase
        // and are not accessible.
        // We need a accessible mock of the controller to replace the protected methods
        // and variables with public ones.
        //
        // getAccessibleMock extends given class with 
        // _set, _setRef, _setStatic, _get and _getStatic methods
        // With this methods it is possible to access the before protected methods and variables
        $this->accessibleFixture = $this->getAccessibleMock(
            '<Vendor>\\<Extension>\\Controller\\ClientController',
            // We don't want PHPUnit replaces all methods with stubs
            // In this case would no own function tested
            // We have to use a dummy function
            array('dummy'),
            array(),
            '',
            FALSE
        );
        // Mock of the view
        $this->accessibleFixture->_set(
            'view',
            $this->getMock('TYPO3\\Fluid\\View\\TemplateView'),
            array(),
            array(),
            '',
            FALSE
        );
        // Mock of the repository
        $this->mockClientRepository = $this->getMock(
            '<Vendor>\\<Extension>\\Domain\\Repository\\ClientRepository',
            array(),
            array(),
            '',
            FALSE
        );
    }

    /**
     * Tear down
     */
    public function tearDown() {
        unset($this->accessibleFixture, $this->mockClientRepository);
    }

    /**
     * Test for listing all clients
     *
     * @test
     */
    public function listActionFindAllClients() {
        $mockQueryResult = $this->getMock(
            'TYPO3\\CMS\\Extbase\\Persistence\\Generic\\QueryResult',
            array(),
            array(),
            '',
            FALSE
        );
        $this->accessibleFixture->_get('clientRepository')->expects($this->once())
            ->method('listAction')
            ->will($this->returnValue($mockQueryResult));
        $this->accessibleFixture->_get('view')->expects($this->once())
            ->method('assign')
            ->with($this->equalTo('clients'),$this->equalTo($mockQueryResult)
        );
        $this->fixture->listAction();
    }

}
?>


I get PHP Fatal error:  Call to a member function expects() on a non-object in /.../Tests/Unit/Controller/ClientControllerTest.php on line 99
This is $this->accessibleFixture->_get('mockClientRepository')->expects($this->once())

Any tips how to solve this problem? 

I try this in setUp()
        $this->accessibleFixture->injectClientRepository($this->mockClientRepository);

Thank you for helping.
