python学习笔记（接口自动化框架 V2.0）

这个是根据上次框架版本进行的优化

用python获取excel文件中测试用例数据

通过requets测试接口、并使用正则表达式验证响应信息内容

生成xml文件测试报告

版本更新内容：

1. 整理了CreateTest.test_main()流程逻辑

2. 优化了testcase.xls文件格式

3. 添加了生成XML文件测试报告

代码如下：

# -*- coding: utf_8 -*-

import json

    def __init__(self):

import time
from createtest import CreateTest

start = time.clock()
CreateTest.test_main()
end = time.clock()

print "接口自动化脚本运行时间：%.03f seconds" % (end - start)

 运行后自动生成 当前时间的xml文件 如下：
