我想为Symfony 5.3应用程序的phpunit-tests定义一个功能测试用例，该应用程序需要容器中的私有服务security.password_hasher。
我得到以下例外

1. App\Tests\Functional\SiteResourceTest::testCreateSiteSymfony\Component\DependencyInjection\Exception\ServiceNotFoundException：编译容器时，security.password_hasher服务或别名已被删除或内联。您应该将其公开，或者停止直接使用容器并使用依赖注入。
   我遵循了文档中关于在测试中检索服务的说明
   我做错了什么？我该怎么解决这个问题？

class CustomApiTestCase extends ApiTestCase
{
    protected UserPasswordHasher $passwordHasher;

    protected function setUp(): void
    {
        // (1) boot the Symfony kernel
        self::bootKernel();

        // (2) use static::getContainer() to access the service container
        $container = static::getContainer();

        // (3) run some service & test the result
        $this->passwordHasher = $container->get('security.password_hasher');
    }

    protected function createUser(
        string $email,
        string $password,
    ): User {
        $user = new User();
        $user->setEmail($email);

        $encoded = $this->passwordHasher->hash($password);
        $user->setPassword($encoded);

        $em = self::getContainer()->get('doctrine')->getManager();
        $em->persist($user);
        $em->flush();

        return $user;
    }

    protected function createUserAndLogIn(Client $client, string $email, string $password): User
    {
        $user = $this->createUser($email, $password);
        $this->logIn($client, $email, $password);

        return $user;
    }


    protected function logIn(Client $client, string $email, string $password)
    {
        $client->request('POST', '/login', [
            'headers' => ['Content-Type' => 'application/json'],
            'json' => [
                'email' => $email,
                'password' => $password
            ],
        ]);
        $this->assertResponseStatusCodeSame(204);
    }
}
