接口测试（二） 优化项目分层及cookies值带入

整个项目分层如图

然后上代码

然后配置文件的xlsx文件格式

注意点：

　　　　1.用例的expected一栏，也就是预期结果一栏要注意参数是否有类似时间戳的不断变更的参数，然后根据这个参数的重要性来选择是添加还是删去

　　　　2.返回值如果有json格式注意和预知结果格式的一致性，我这次就是在这里被绊了一下，单双引号要注意

　　　　3.原本的用例格式没有最后一栏也就是result_data，但是这次用例涉及存取金额，所以我还是加了一行用来检查数据的正确性

　　　　4.搬代码的朋友注意下我的配置文件中，邮件模块是没有写参数的，用的变量代替，所以要用的话要自己改一下

　　　　5.setupclass和tearDownclass要配合@classmethod装饰器使用，是一次运行只执行一次的用法，要牢记，感觉以后会用不少次

　　　　6.读取cases表也可以写成类属性，不写成字典形式，下一次更新我估计会把字典模式更换成类属性模式

后记：　

　　　　1.可以添加表连接模块，添加sql语句栏，用作表查询结果断言

　　　　2.result_data栏的写入可以优化一下，如果为None则不写入，否者写入产生变化的参数（最简单的方法是新增测试表栏，也可以新增一个数据库表单，建立关联关系，然后根据数据库表单查询并写入）

 更新：

　　　　1.更新用例从单表变更为多表，但是运行时的参数带入还待优化，现在的运行是一个表运行一次

　　　　2.删除用例中的for循环，优化读取xlsx的模块方法Date_test_list

　　　　3.更新对象传参
