the PHPUnit test of a uri fails while the request succeeded in the browser - phpunit

Question

My application is on Symfony 4.4, PHP 7.4.
My composer.json :

"conflict": {

"extra": {
"symfony": {

}
}
}
There is the method controller I want to test:
<?php
namespace App\Controller;
use App\Entity\User;
use App\Form\UserType;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Component\Security\Core\Encoder\UserPasswordEncoderInterface;
class UserController extends AbstractController
{
/**
* list all users.
*
* #Route("/users", name="user_list")
*
* #return Response
*/
public function list(): Response
{
return $this->render('user/list.html.twig', ['users' => $this->getDoctrine()->getRepository(User::class)->findAll()]);
}
}
Then a test it with PHPUnit
<?php
namespace App\Tests\Controller;
use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;
/**
* #internal
* #coversNothing
*/
class UserControllerTest extends WebTestCase
{
/**
* testIndex.
*/
public function testUserList(): void
{
$client = static::createClient();
$client->request('GET', '/users');
$this->assertTrue($client->getResponse()->isSuccessful());
}
}
In the browser, the request is successfull (The page display without error, with 200 HTTP code status, no errors in the profiler)
But, when I run PHPUnit, the test fails with $client->getResponse()->getStatusCode() = 500 !!!!
How can I fix that ?
Thank you for your answers

Answer 1

I solved my problem !
When a had the idea to display the page with the test environment, I get the error:
An exception occurred in driver: SQLSTATE[HY000] [2002] Aucune connexion n’a pu être établie car l’ordinateur cible l’a expressément refusée.
So I solved the problem creating a database for the test environment, in defined my .env.test.
