问题:PHPUnit 在使用 Symfony2 成功完成测试后抛出错误消息

我们刚刚开始对我们的 CI 应用程序进行单元测试;我们编写的第一个测试运行通过,但 PHPUnit 总是在最后抛出错误消息:

user@server:~/public$ phpunit -c app/ --strict src/Acme/Bundle/SomeBundle/Tests/Controller/SomeControllerTest.php 
PHPUnit 3.6.11 by Sebastian Bergmann.

Configuration read from /var/www/user/htdocs/public/app/phpunit.xml.dist

..

OO (2 tests, 2 assertions)
PHP Fatal error:  Exception thrown without a stack frame in Unknown on line 0

到目前为止,唯一的提示是它仅在一个(或多个)测试使用 [see below] 在页面上发出请求时发生,因此它可能在某种程度上与会话相关。

$client = static::createClient();
$container = $client->getContainer();
$uri = $container->getParameter('url_frontend') . '/';
$client->request('GET', $uri);

这是我们的phpunit.xml.dist的链接

更新:

我设法获得了更多关于错误本身的信息:

1) Acme\Bundle\SomeBundle\Tests\Controller\SomeControllerTest::testIndexResponseStatusCode
RuntimeException: PHP Fatal error:  Uncaught exception 'ErrorException' with message 'Warning: Unknown: Failed to write session data (user). Please verify that the current setting of session.save_path is correct (/tmp/sessions) in Unknown line 0' in /var/www/user/htdocs/public/vendor/symfony/src/Symfony/Component/HttpKernel/Debug/ErrorHandler.php:67
Stack trace:

解答

我们的一位开发人员(经过多次咒骂和诅咒)解决了这个问题,错误在于FOS\FacebookBundle\Facebook\FacebookSessionPersistence确切地说是构造函数启动了自己的会话:

public function __construct($config, Session $session, $prefix = self::PREFIX)
{
    $this->session = $session;
    $this->prefix  = $prefix;
    $this->session->start(); // he starts a session

    parent::__construct($config);
}

所以我们只需要编写你自己的 Facebook Session Persistence 类:

namespace Acme\Bundle\UserBundle\Facebook;

use FOS\FacebookBundle\Facebook\FacebookSessionPersistence as BaseFacebookSessionPersistence;
use Symfony\Component\HttpFoundation\Session;

/**
 * Quick (and dirty) fix for running tests using FosFacebookBundle.
 * only use this class, while testing the application with phpunit
 *
 * @see https://github.com/FriendsOfSymfony/FOSFacebookBundle/issues/79
 */
class FacebookSessionPersistence extends BaseFacebookSessionPersistence
{
    public function __construct($config, Session $session, $prefix = self::PREFIX)
    {
        $this->session = $session;
        $this->prefix  = $prefix;

        // don't start session or call parent constructor
        //$this->session->start();

        //parent::__construct($config);

    }
}

并将其添加到测试配置中:

# quick workaround as the fb class fails the test as it calls session->start in the construct   
# @see https://github.com/FriendsOfSymfony/FOSFacebookBundle/issues/79
fos_facebook:
    class:
        api: Acme\Bundle\UserBundle\Facebook\FacebookSessionPersistence   

希望对后代有所帮助...
