Symfony4/Behat 注入(inject)功能不工作 "you have requested a non-existen service"

Question

对于测试用例，我需要能够使用现有服务，但该服务不能在我的 behat 上下文中使用:

上下文:

/**
class CustomContext extends MinkContext implements KernelAwareContext {

    # ...

     * @param EntityManagerInterface $em
     * @param HttpCallResultPool $httpCallResultPool
     * @param SessionInterface $session
     * @param CustomService $customService
     * @param string $evaluationMode
     */
    public function __construct(
        EntityManagerInterface $em,
        HttpCallResultPool $httpCallResultPool,
        SessionInterface $session,
        CustomService $customService,
        string $evaluationMode = 'javascript'
    ) {
        $this->em = $em;
        $this->client = new Client();
        $this->inspector = new JsonInspector($evaluationMode);
        $this->httpCallResultPool = $httpCallResultPool;
        $this->session = $session;
        $this->customService= $customService;
    }

behat.yaml:

# ...
    Behat\Symfony2Extension:
      kernel:
        bootstrap: 'config/bootstrap.php' 
        path: 'src/Kernel.php'  
        class: 'App\Kernel' 
        env: dev 
        debug: false 

# ...
suites:
    default:
      contexts:
        - App\CustomContext:
            em: '@doctrine.orm.default_entity_manager'
            session: '@session'
            customService: '@App\Service\CustomService'

Fehlermeldung:

In Container.php line 289:
                                                                                                                             
  You have requested a non-existent service "App\Service\CustomService".

有人可以提供帮助或知道为什么会显示此错误消息吗？该服务确实在使用的 Controller 中工作。所以服务本身应该没有错误，只是将此服务注入(inject) behat。

您可以按照此处的说明注入(inject)容器并访问私有(private)服务:https://symfony.com/blog/new-in-symfony-4-1-simpler-service-testing
