测试用户连接到Symfony / PhpUnit

Question

在我的控制器中，我使用security.token_storage服务将用户连接起来：

$client = $this->container->get('security.token_storage')->getToken()->getUser(); $username = $client->getNom()." ".$client->getPrenom();

在功能测试中，我尝试登录用户以在控制器中检索它，但是如果在内部调试，则表明我是匿名的：

private function logIn()
{
    $client = static::createClient();
    $firewallName = 'main';
    $token = new UsernamePasswordToken("admin", "admin", "main", array());
    static::$kernel->getContainer()->get('security.token_storage')->setToken($token);
    $session = static::$kernel->getContainer()->get('session');
    $session->set('_security_'.$firewallName, serialize($token));
    $session->save();
    $cookie = new Cookie($session->getName(), $session->getId());
    $client->getCookieJar()->set($cookie);

    return $client;
}

public function testIndex()
{
    $client = $this->logIn();
    $crawler = $client->request('GET', '/');
    $login = $crawler->filter("#username_index")->text();
    $this->assertEquals($login, 'ADMIN NOM Admin Prenom');
}

我如何将我的测试用户传递给我的主要代码？
