Symfony 单元测试和容器

Question

在 Symfony 2 中进行单元测试时，我正在测试的控制器没有接收到服务容器，导致测试失败并使用旧的 Call to a member function get() on a non-object

我不能从测试控制器使用 $this->forward，因为它也没有服务容器。

我找到了这个参考，但似乎我会因为错误的原因使用它，有没有人有这方面的经验？

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);
    }

}

这是失败的客户端控制器部分

<?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);

    }    
}

我认为控制器没有获取容器的原因是因为您尝试直接实例化并与之交互，而不是使用客户端模拟请求（请参阅 Symfony2 书的Testing section 中的功能测试部分)。

你需要更多这样的东西（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）。
