PHPUnit和Symfony2无法访问全局变量

这是我的phpunit.xml文件

<?xml version="1.0" encoding="UTF-8"?>

从注释中可以看出，考虑到我遵循了文档，我的类似乎没有看到phpunit.xml文件中定义的globals

你有什么想法吗？我错过什么了吗

谢谢大家!

在symfony2中，默认的phpunit.xml不是app/phpunit.xml中的phpunit.xml，而是应用程序根目录中的phpunit.xml。将所有值都放在那里，一切正常。

您检查了$\u服务器了吗？@RenatoMendesFigueiredo它对所有变量都做了相同的操作，现在它让我找到了下面的答案，谢谢！你检查了$\u服务器了吗？@RenatoMendesFigueiredo它对所有变量都做了相同的检查，现在它让我得到了下面的答案，谢谢！
