Symfony 单元测试和容器

Question

在 Symfony 2 中进行单元测试时，我正在测试的 Controller 未接收到服务容器，导致测试失败，并出现旧的调用非对象上的成员函数 get()

我无法从测试 Controller 使用 $this->forward，因为它也没有服务容器。

我找到了这个引用资料，但似乎我会出于错误的原因使用它，有人有这方面的经验吗？

http://symfony.com/doc/current/book/testing.html#accessing-the-container

编辑:这是我的测试:

<?php

namespace HvH\ClientsBundle\Tests\Controller;

use HvH\ClientsBundle\Controller\ClientsController;

use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\HeaderBag;
use Symfony\Component\HttpFoundation\Session;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;

class ClientsControllerTest extends WebTestCase
{

    public function testGetClientsAction()
    {

        $client = static::createClient();
        $container = $client->getContainer();
        $session = $container->get('session');
        $session->set('key', 'value');
        $session->save();

        $request = new Request;
        $request->create('/clients/123456', 'GET', array(), array(), array(), array(), '');

        $headers['X-Requested-With'] = "XMLHttpRequest";
        $request->headers->add($headers);

        /* This doesn't work */
        /*
        $controller = new Controller;
        $status = $controller->forward( 'HvHClientsBundle:Clients:getClients', array('request' => $request) );        
        */

        $clients_controller = new ClientsController();
        $status = $clients_controller->getClientsAction($request);

        $this->assertEquals(200, $status);
    }

}

这是客户端 Controller 失败的部分

<?php

namespace HvH\ClientsBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use HvH\APIschemaBundle\Controller\Validation;


//FOSRestBundle
use FOS\RestBundle\View\View;

class ClientsController extends Controller
{

    //Query all clients
    public function getClientsAction(Request $request)
    {
        $request_type = $request->headers->get('X-Requested-With');

        if($request_type != 'XMLHttpRequest') {
            return $this->render('HvHDashboardBundle:Dashboard:dashboard.html.twig' );          
        }

        //get any query strings
        $query_strings = $request->query->all();
        $definition = $this->get("service.handler")->definition_handler(__CLASS__, __FUNCTION__);
        //once data has been prepared 
        return $this->get('fos_rest.view_handler')->handle($view);

    }    
}

我认为 Controller 没有获得容器的原因是因为您试图实例化它并直接与其交互，而不是使用客户端模拟请求(请参阅 Symfony2 书中的 Testing section 中的功能测试部分)。

您需要类似这样的东西(不确定路线是否正确):

public function testGetClientsAction()
{
    $client = static::createClient();

    $client->request(
        'GET', '/clients/123456', 
        array(), /* request params */ 
        array(), /* files */
        array('X-Requested-With' => "XMLHttpRequest"),
    );

    $this->assertEquals(200, $client->getResponse()->getStatusCode());  
}

另请注意，request() 方法返回一个爬虫实例，该实例提供辅助方法来验证响应的内容(如果需要)。
