那么，当我们想要处理ajax时，我们必须添加一些睡眠指令，即使最终用户实际上“等待”某些东西我也真的不喜欢这个，我认为它应该是非常基础的-ajax请求。
我真的很想知道为什么它还不存在，我写了一些改编，并希望在可能的PR之前得到你的反馈：

对于好奇的人，我没有发送PR但最终实现了特性https://github.com/Troopers/BehatContexts/blob/master/src/Troopers/BehatContexts/Context/SpinMinkContextTrait.php）来实现behat文档的建议：
正如Behat所说：
通常情况下，特别是在使用Mink测试Web应用程序时，您会发现Behat比Web应用程序跟上的速度更快 - 它会在页面有机会加载之前尝试单击链接或执行操作，因此结果在失败的测试中，否则会通过。为了缓解这个问题，我们可以使用旋转函数，重复尝试和操作或测试条件，直到它工作。本文着眼于将其应用于Mink，但该技术适用于使用Behat的任何测试。 阅读文档
