KeyError： 'browser' 与 Splinter 和行为自动化测试

Question

我遵循了此处的说明：http://shon.github.io/2014/06/19/ui_testing_and_bdd.html关于使用Behaving设置Splinter以运行自动测试。我可以成功运行测试，但在测试结束时，它会抛出一个错误：

KeyError："浏览器"

而且它不会继续测试任何附加的功能文件。我对python还很陌生，需要一些帮助来解决这个问题。

Exception KeyError: 'browser'

KeyError: 'browser'

Answer 1

我发现了这个问题。它与功能文件结构有关。功能文件丢失：

 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/behaving
