Testion controler method in symfony (phpUnit)

Question

i need some help i want to write a unit test about a controler method , i have searched for examples and tested a lot of method's but none of them has worked:

Here is my controller:

class ComputerController extends Controller
{
/**
     * @Route("/list-computers.html", name="back_computer_list")
     * @return RedirectResponse|Response
     */
    function listComputerAction()
    {
        $ad = $this->get("ldap_service");
        $computers = $ad->getAllComputer();
        return $this->render('BackBundle:Computer:list.html.twig', array(
            "computers" => $computers,
        ));
    }

I have tried to test it with mock like this:

class ComputerController extends Controller
{
    /**
     * @var EngineInterface
     */
    private $templating;


    public function setTemplating($templating)
    {
        $this->templating = $templating;
    }
and i have created a test method:

class ComputerControllerTest extends  TestCase {

    public function testlistComputerAction(){
        $templating = $this->getMockBuilder('BackBundle\Controller\ComputerController')->getMock();
        $computers = [1,2];
        $templating->expects($this->once())
            ->method('render')
            ->with('BackBundle:Computer:list.html.twig', array(
                "computers" => $computers))
            ->will($this->returnValue( $computers));

        $controller = new ComputerController();
        $controller->setTemplating($templating);

        $this->assertEquals('success', $controller->listComputerAction());
    }

When i start executing phpunit , i have this warning"Trying to configure method "render" which cannot be configured because it does not exist, has not been specified, is final, or is static"

I would be thankful if someone has an idea about this

I tried to Test a method in ldapService : Here is the method's of the service that i want to test

/**
     * @return bool|resource
     */
    public function getLdapBind()
    {
        if (!$this->ldapBind) {

            if ($this->getLdapConnect()) {
                $this->ldapBind = @ldap_bind($this->ldapConnect, $this->ldapUser, $this->ldapPass);
            }
        }
        return $this->ldapBind;

    }


    /**
     * @param $ldapUser
     * @param $password
     * @return bool
     */
    function isAuthorized($ldapUser, $password)
    {
        $result = false;
        if ($this->ldapConnect) {
            $result = @ldap_bind($this->ldapConnect, $ldapUser, $password);
        }
        return $result;
    }

Here is the test (using Mock):

<?php

namespace BackBundle\Tests\Service;

use PHPUnit\Framework\TestCase;
use BackBundle\Service\LdapService;
use PHPUnit_Framework_MockObject_InvocationMocker;

class LdapServiceTest extends  TestCase {



  public function testgetLdapConnect()
    {
//        $LdapService = new LdapService();
        $ldapMock = $this->getMockBuilder( 'LdapService')->setMethods(['getLdapBind'])->disableOriginalConstructor()->getMock();
        $ldapMock->expects($this->once())
//                ->method()
                ->with(array('ldap_bind', 'mike', 'password'))
            ->will($this->returnValue(true));

        $ldapMock->isAuthorized('mike', 'password');
    }
}

But i have a warning that i can't resolve : "Method name matcher is not defined, cannot define parameter matcher without one"

If someone , has an idea about that please

Answer 2

Honestly, there is nothing useful to test in that three-line controller. #1 is the service container, and #3 is the Twig subsystem. Line #2 can be unit tested on it's own.

With more complex controllers, I have found that making them a service where all the dependencies are passed in, either by constructor, or into the action itself does make slightly more complex controllers quite easy, but very few need that anyway.
