接口测试TOOL

实现目标：

以excel接口用例为依据，实现接口的自动化测试，并生成结果

使用场景：

1.根据接口测试用例模板，编写相应用例
2.调用脚本，自动化执行用例，并自动生成用例结果

脚本分析：

1.使用的库方法：表格处理：xlrd，xlwt，xlutils 接口处理：cookielib， urllib， urllib2
2.各文件功能：
读取EXCEL用例中和接口相关的数据，筛选出了接口地址、请求头、请求参数、预测结果
将获取的参数拼接成请求，即执行用例获取接口返回数据

脚本间关系

用例模板： （ 提取码：8fnk ）

1. 用例在TestCase表单中填写
2. 请使用xls格式保存。

脚本代码：
