Testion controler method in symfony (phpUnit) - symfony

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.
