基于HttpRunner，解析swagger数据，快速生成接口测试框架

使用HttpRunner默认生成的项目是这样的

　　命令：httprunner --startproject  项目名称

so，根据这个项目的目录结构，使用python解析swagger接口参数，可以快速生成api、testcases、testsuites文件夹中用到的json文件

运行后的目录是这样的

　　api目录

　　　　按swagger中的tags区分为多个文件夹，每个文件夹下包含各自的api文件

　　

　　testcases目录

　　　　按swagger中的tags区分为不同的json文件，每个文件包含所有的api接口

　　

　　testsuites目录

　　　　测试用例集，组织运行所有的测试用例

　　

　这样，接口测试框架的简易架子就有了。接下来，需要补充api接口文件数据

　

　略

　

运行结果

　　

　HttpRunner自带的report

　　

附lib目录下的代码

　　swagger.py

具体业务场景的测试，可以按照导入.har文件的方法快速生成，总之还是挺便捷的。
