firefox - 此页面要求您确认是否要离开

Question

我正在我的站点安装上运行行为测试。运行测试时我收到以下错误。我转而使用 Firefox，因为我在使用新的 chromedriver 2.10 时遇到了问题。我可以解决这个问题吗？

错误消息:

你(官方)对此不走运。 Behat/Mink 不支持对话处理，并且在找到对话时会抛出异常，因为它对此无能为力，并且会阻止后续步骤。有一个long standing issue on github这解释了原因，我同意亚历山大的最后评论:

Nowadays browser dialogs are considered bad UX and are replaced by nice looking modal windows (at least on websites I was doing), which already can be handled.

非官方地，如果您直接调用 Selenium 驱动程序，this gist 是可能的。是如何做到这一点的最好例子。如果您搜索“selenium modal window”而不引用 Behat，您可以找到更多相关信息。
