Symfony BehatContext和MinkContext之间的混淆

我试图在我的Symfony 2.3项目中进行BDD，但似乎遇到了一些不一致之处

根据我是使用BehatContext还是MinkContext作为FeatureContext类的基类，我会得到不同的结果

如果我使用：

class FeatureContext extends BehatContext 

一切都很好。但是，如果我使用：

class FeatureContext extends MinkContext

我得到了一些错误，这使得MinkContext看起来不再喜欢系统自己生成的正则表达式。你能帮我理解一下吗

如果需要访问Mink会话（用于浏览器自动化），请扩展

RawMinkContext

不要直接使用痛风

BehatContext

是一个基本上下文，当您不需要貂皮时，它将是您自己的大多数上下文的默认选择

MinkContext

是一个专门的上下文，允许您访问Mink会话（与

RawMinkContext

相同）。但是，它还包含一些基本步骤定义。这就是为什么您永远不应该扩展它，而应该将它用作子上下文。您只能扩展它一次，因为步骤定义不能重复

这个问题与您的另一个问题非常相似（请看那里的水貂用法示例）：

使用Behat并不意味着您正在遵循BDD。要了解更多信息，请阅读以下书籍：
