我使用Twig_Environment来渲染html邮件以发送。我有一个NotificationService类，其他服务使用它来发送这些邮件。
在正常使用情况下，一切都正常工作，但自从更新到2.8版本后，单元测试失败并出现以下错误信息：
Symfony\Component\DependencyInjection\Exception\RuntimeException: You have requested a synthetic service ("kernel"). The DIC does not know how to construct this service
我调试了StackTrace，问题似乎出在Twig_Environment上（它使用注入kernel的file_locator）
/**
* Notification Service Class
*
* @DI\Service("app.service.notification")
*/
class NotificationService extends Generic
{
/**
* @var \Twig_Environment
*/
protected $twig;
/**
* @var \Swift_Mailer
*/
protected $swiftMailer;
/**
* @var string
*/
protected $mailTemplate = 'VendorAdminBundle:Email:system2.html.twig';
/**
* @param \Swift_Mailer $swiftMailer
* @param \Twig_Environment $twig
*
* @DI\InjectParams({
* "swiftMailer" = @DI\Inject("mailer"),
* "twig" = @DI\Inject("twig")
* })
*/
public function __construct(\Swift_Mailer $swiftMailer, \Twig_Environment $twig)
{
$this->twig = $twig;
$this->swiftMailer = $swiftMailer;
}
/**
* Send notification mail to Manager
* @param UserEntity $manager
* @param array $contacts
*/
public function notifyManager(UserEntity $manager, array $contacts)
{
$subject = 'Lorem Ipsum';
$templateFile = "AppBundle:Email:notifyManager.html.twig";
$templateContent = $this->twig->loadTemplate($templateFile);
$body = $templateContent->render(array(
'user' => $manager,
'contacts' => $contacts,
'subject' => $subject,
));
$this->sendMail($body, $subject, $manager);
}
}
你有解决这个问题的任何指针吗？
编辑：（按要求）
class NotificationTest extends DoctrineTestCase
{
/**
* @var \App\Service\Notification
*/
protected $service;
public function setUp()
{
$this->markTestSkipped('Problem with twig env');
$this->loadFixturesFromDirectory(__DIR__ . '/DataFixtures');
$this->loginUser('admin', $this->getUser(1));
$this->service = $this->container->get('neos.service.notification'); // <-- exception thrown here
}
[test methods]
}

{
return $this->container->get($this->entityManagerServiceId);
}
}
编辑3： 在过去的某些时候，获取内核似乎已发生变化。 请参见：http://symfony.com/doc/master/cookbook/testing/doctrine.html
我将我的构造函数从以下内容更改为：
public function __construct($name = null, array $data = array(), $dataName = '')
{
parent::__construct($name, $data, $dataName);
if (!static::$kernel) {
static::$kernel = self::createKernel(array(
'environment' => $this->environment,
'debug' => $this->debug,
));
static::$kernel->boot();
static::$kernel->getContainer()->set('kernel', static::$kernel); //<--- Added - but doesnt help
}
$this->container = static::$kernel->getContainer();
$this->em = $this->getEntityManager();
}
致：
public function __construct($name = null, array $data = [], $dataName = '')
{
parent::__construct($name, $data, $dataName);
self::bootKernel();
$this->container = static::$kernel->getContainer();
$this->em = $this->getEntityManager();
}
但不幸的是，它无法解决测试使用Twig_Env时出现的运行时异常问题。
DoctrineTestCase类？我有一种感觉，设置内核或获取容器时可能会出现问题。 - Dan Mironis
