无法使用phpunit扩展symfony中的泛型类

Question

我有头等舱：

namespace Tests\AppBundle\EntitiesConstraints;

use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;
use Symfony\Component\Validator\Validation;

class EntityTest extends WebTestCase
{
...}

和第二个：

namespace Tests\AppBundle\EntitiesConstraints;

use AppBundle\Entity\AnnonceSuperClasse;
use Symfony\Component\Validator\Validation;
use Tests\AppBundle\EntitiesConstraints\EntityTest;

class AnnoncesAssertTest extends EntityTest
{
...}

问题是，显然，我无法扩展EntityTest。

我收到此消息：

  

严重错误：类'Tests \ AppBundle \ EntitiesConstraints \ EntityTest'   找不到   C：\ wamp \ www \ projets \ Tabadoul \ tests \ EntitiesConstraints \ AnnoncesAssertTest.php   在第9行

提前感谢您的帮助！
