我按照此处的说明进行操作：http: //shon.github.io/2014/06/19/ui_testing_and_bdd.html 关于设置 Splinter with Behave 以运行自动化测试。我能够成功运行测试，但在测试结束时，它会抛出一个错误说：

KeyError：'浏览器'

并且它不会继续测试任何其他功能文件。我对python很陌生，需要一些帮助来解决这个问题。

Exception KeyError: 'browser'

我发现了这个问题。它与Feature文件结构有关。缺少功能文件：

 Background:
    Given a browser

这还需要根据此处的信息更改 environment.py 文件：https ://github.com/ggozad/behave
