Symfony 4. 允许获取私有服务的特殊容器

Question

页面上https://symfony.com/blog/new-in-symfony-4-1-simpler-service-testing站着

// gets the special container that allows fetching private services
$container = self::$container;

但它在功能测试中对我没有影响。只有当我将服务定义为公开时，我才能使用$container->set('service.mail', $someService);

这里有什么问题？

Answer 1

您是否使用文件 services_test.yaml？

我添加了所有需要包含在测试中的服务我向您展示了我的文件的一部分：

services:
    _defaults:
        public: true

    # If you need to access services in a test, create an alias
    # and then fetch that alias from the container. As a convention,
    # aliases are prefixed with test. For example:
    #
    # test.App\Service\MyService: '@App\Service\MyService'

    test.app.service.user_management.user_service:
        alias: App\Service\UserManagement\UserService

    test.app.service.weight.weight_service:
        alias: App\Service\Weight\WeightService

当你这样做时，其余的应该就位。
