Symfony 2股票控制器测试失败，错误为“未定义的索引:HTTP_HOST”

我想知道是否有人能解决这个错误。我刚刚在Symphony 2项目中设置了PhpUnit 4.3.*和Doctrine Fixtures Bundle，当我运行bin/phpunit -c app/时，我会出现以下错误。这些是Symfony 2代码生成器自动生成的控制器测试，所以我认为它们在任何情况下都应该通过/有效。我有预感phpunit的配置/安装可能有问题，但我不确定。。。

Project'AdminBundle'Tests'Controller'DefaultControllerTest::testIndex
Undefined index: HTTP_HOST

记录在案，我的composer.json是：
