How to Log User from Functional Testing with Symfony - symfony

Question

I use FOSUserBundle for my User Authentication
I have a controller, let's call it adminController which is reserved for User granted User::ADMIN_ROLE
Everything works fine but I have an error when I try to write my functional Test
Inside my AdminControllerTest I have a method that try to test a page that need User::ADMIN_ROLE
My testAdminAccess() method
public function testAdminAccess()
{
$session = $this->client->getContainer()->get('session');
// the firewall context defaults to the firewall name
= 'main';
$user = $this->getUserByUsername('admin#yopmail.com');
$token = new UsernamePasswordToken($user, null, $firewallContext, $user->getRoles());
$session->set('_security_'.$firewallContext, serialize($token));
$session->save();
$cookie = new Cookie($session->getName(), $session->getId());
$this->client->getCookieJar()->set($cookie);
$this->client->followRedirects();
$crawler = $this->client->request(
'GET',
'http://localhost/admin'
);
dump($crawler);
}
I'm always redirected to my login page
How can I keep the session to access some page that's protected by a specific Role?

The best is to login the user normally submitting the username and password like a standard user would do, I use a function like this (adapt your paths):
/**
* Log the test user for the connected tests.
*/
public function login(string $username = null, string $password = null): KernelBrowser
{
$client = static::createClient();
// Login page
$client->request('GET', '/en/login/');
$this->assertTrue($kernelBrowser->getResponse()->isOk());
// Auth
$token = $client->getContainer()->get('security.csrf.token_manager')->getToken('authenticate');
$client->request('POST', '/login_check', [
'_csrf_token' => $token,
'_username' => $username ?? 'test',
'_password' => $password ?? 'test',
'_remember_me' => 'on',
]);
$this->assertTrue($client->getResponse()->isRedirect());
$client->followRedirect();
return $client;
}
