How to mock in Symfony functionnal tests? - php

Question

I'm creating functionnal tests on a Symfony 3.4 application.
<?php
namespace AppBundle\Tests\Controller;
use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;
use Symfony\Component\Security\Core\Authentication\Token\UsernamePasswordToken;
use Symfony\Component\BrowserKit\Cookie;
use Symfony\Component\HttpFoundation\Response;
class UserControllerTest extends WebTestCase
{
/**
* Connect to the website while being logged in
* Logs in with (admin, password : a)
*/
public function connection()
{
$client = static::createClient();
$container = static::$kernel->getContainer();
$session = $container->get('session');
// Get the user (has to exist in the database)
$person = self::$kernel->getContainer()->get('doctrine')->getRepository('AppBundle:User')->findOneByUsername('admin');
$token = new UsernamePasswordToken($person, null, 'main', $person->getRoles());
$session->set('_security_main', serialize($token));
$session->save();
$client->getCookieJar()->set(new Cookie($session->getName(), $session->getId()));
// Return the client
return $client;
}
public function accessEditPage()
{
$client = $this->connection();
$crawler = $client->request('GET', '/user/');
$this->assertSame(Response::HTTP_OK, $client->getResponse()->getStatusCode());
$this->assertContains(
'Liste des utilisateurices',
$client->getResponse()->getContent()
);
// Select the button of the user created for the test
// Wont work if there are already more than 10 users in the database
$link = $crawler
->filter('tr > td > a:contains("")')
->last()
->link()
;
$crawler = $client->click($link);
return array($client,$crawler);
}
/**
* Create a new user
*/
public function testCreate()
{
$client = $this->connection();
$crawler = $client->request('GET', '/user/new');
$this->assertSame(Response::HTTP_OK, $client->getResponse()->getStatusCode());
// Vérifie si la page affiche le bon texte
$this->assertContains(
'Enregistrer',
$client->getResponse()->getContent()
);
// Select the form and fill its values
$form = $crawler->selectButton(' Créer')->form();
$values = $form->getPhpValues();
$values['appbundle_user']['username'] = 'Jean';
$values['appbundle_user']['plainPassword']['first'] = 'motdepasse';
$values['appbundle_user']['plainPassword']['second'] = 'motdepasse';
$crawler = $client->request($form->getMethod(), $form->getUri(), $values,$form->getPhpFiles());
$crawler = $client->followRedirect();
$this->assertContains(
'Jean',
$client->getResponse()->getContent()
);
}
}
Currently, my Controller tests create databases entries and depends on existing ones and that's a problem.
I want to mock the repositories used in the controller to avoid creating entries when I test my controllers but I haven't found helpful documentation about it. As I can't find documentation, I also wonder if what I want to do is a good practice or not.
