我正在尝试在我的Symfony 2.3项目中进行BDD，并且似乎正在努力解决一些不一致问题。
根据我是否使用BehatContext或MinkContext作为FeatureContext类的基类，我得到的结果不同。
如果我使用：
class FeatureContext extends BehatContext
class FeatureContext extends MinkContext
我得到的错误使得它看起来像MinkContext不再喜欢我的正则表达式而不再是系统自己生成的。你能帮我理解一下：

如果您需要访问Mink会话（用于浏览器自动化），请扩展RawMinkContext。
不要直接使用Goutte。
BehatContext是一个基本的上下文，当你不需要Mink时，它将是你自己大多数情境的默认选择。
MinkContext是一个专门的上下文，可让您访问Mink会话（与RawMinkContext相同）。但是，它还包含一些基本步骤定义。这就是为什么你永远不应该扩展它，而是将它用作子上下文。您只能将其扩展一次，因为步骤定义不能重复。
问题与您的其他问题非常相似（查看Mink用法示例）：What is wrong with my FeatureContext?
使用Behat并不意味着您正在关注BDD 。要了解有关它的更多信息，请阅读以下书籍：
