php – 在symfony 2功能测试中找不到路由

<?php

namespace WebSiteMainBundleTestsController;

use SymfonyBundleFrameworkBundleTestWebTestCase;

class ProductControllerTest extends WebTestCase
{

    public function testPageContents()
    {
        $domCategoryLinksExpr = '.catalog-col-block > ul > li > a';

        $client = static::createClient();

        $crawler = $client->request('GET','/catalog/');
        $this->assertTrue($client->getResponse()->getStatusCode() == '200');

        $countCategories = $crawler->filter($domCategoryLinksExpr)->count();
        $this->assertTrue($crawler->filter($domCategoryLinksExpr)->count() > 0);

        $categoryLink = $crawler->filter($domCategoryLinksExpr)->eq(rand(1,$countCategories))->link();
        $crawler = $client->click($categoryLink);
    }
}

但是当我运行这个测试时：

phpunit -c app src/WebSite/MainBundle/Tests/Controller/

我懂了：

1) WebSiteMainBundleTestsControllerProductControllerTest::testPageContents
SymfonyComponentHttpKernelExceptionNotFoundHttpException: No route found for “GET /app_dev.php/catalog/psp”
…

/app_dev.php/catalog/psp是$categoryLink-> getUri()的动态值.和
此路由存在且在Web浏览器中正常工作.有任何想法吗？

UPD：

这是我的路由规则：

routing_dev.yml:
   ... 
   _main:
       resource: routing.yml
   ....

routing.yml:
    ....
    WebSiteCategoryBundle:
       resource: "@WebSiteCategoryBundle/Controller/"
       type:     annotation
       prefix:   /    
    ....

src/WebSite/CategoryBundle/CategoryController.php:
    /**
    * @Route("/catalog")
    */
    class CategoryController extends Controller
    {
        /**
        * @Route("/{alias}",name="show_category" )
        * @Template()
        */
        public function showAction( $alias )
        {
           // some action here
        }
    }

它在浏览器中运行良好,但似乎$crowler确实没有看到这个注释规则.

UPD2：问题出现在Symfony 2标准版中缺少的“routing_test.yml”中.
所以我创建它：

routing_test.yml:
    _main:
        resource: routing_dev.yml

和异常消失.谢谢大家.
