php - 如何在 Symfony 5.3 phpunit 测试中访问私有(private)服务？

Question

我想为我的 Symfony 5.3 应用程序的 phpunit-tests 定义一个功能测试用例，它需要来自容器的私有(private)服务 security.password_hasher。

我得到以下异常

1. App\Tests\Functional\SiteResourceTest::testCreateSiteSymfony\Component\DependencyInjection\Exception\ServiceNotFoundException: The security.password_hasher service or alias has been removed or inlined when the container was compiled. You should either make it public, or stop using the container directly and use dependency injection instead.

我按照有关 retrieving services in the test 的文档中的说明进行操作

我做错了什么？我该如何解决这个问题？

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);
    }
}

我不得不重写服务的完整定义以防止在缓存编译期间出现以下错误:

The definition for "security.user_password_hasher" has no class. Ifyou intend to inject this service dynamically at runtime, please markit as synthetic=true. If this is an abstract definition solely usedby child definitions, please add abstract=true, otherwise specify aclass to get rid of this error.

services.yaml

security.user_password_hasher:
    class: Symfony\Component\PasswordHasher\Hasher\UserPasswordHasher
    public: true
    arguments:
      [ '@security.password_hasher_factory' ]
