pycukes 0.2

比库克斯

pycukes是一个类似黄瓜的bdd工具，建立在pyhistorian之上。 PyCukes的创建是为了填补PyHistorian留下的空白，因此可以首先使用文本文件与您的涉众交谈，而不是像PyHistorian这样简单的不可处理的Python文件。

用法

首先，确保您已经安装了Story嫒runner、PyHistorian和PyCukes。 默认情况下，如果您只是从命令行调用pycukes到某个目录中，它将查找stories目录（期望您的故事文件在那里），然后查找step_definitions目录（期望您的步骤定义在那里）。 按照约定，每个故事文件都以.story结尾，比如calculator.story，每个步骤定义都应该以steps.py结尾，比如calculator_steps.py。

所以，假设您有目录树：

|-- calculator
   `-- stories
       |-- calculator.story
       `-- step_definitions
           `-- calculator_steps.py

要运行您的故事，您可以简单地调用：

$ pycukes

或者，如果您可以确切地指定运行的报道：

$ pycukes stories/calculator.story

参数

-s or --stories-dir  --  specify your stories directory
-t or --steps-dir  --  specify your step definitions directory
-n or --no-colors  --  tells pycukes not to show colored output
-c or --colored (default) -- tells pycukes to show colored output
-l or --language (en-us by default) -- specify your story language [en-us and pt-br are supported]

实际示例

目录树：

`-- stories
    |-- bowling_game.story
    `-- step_definitions
        `-- bowling_game_steps.py
