一、测试需求描述
对服务后台一系列的http接口功能测试。
输入：根据接口描述构造不同的参数输入值（Json格式）
输出：字符串（传入的方式+传入的字符串）
http://localhost:8090/lctest/TestServer
二、程序设计
1、Client程序设计
读取Excel配置的测试用例数据
发送参数Json格式给Server，接收Server的返回数据
进行数据比对校验，返回测试结果，将数据插入到Excel中
2、Server端程序设计
接受Client的参数，进行解析
发送返回数据给client
三、实现方法
1、选用Java脚本来驱动测试
2、采用Excel表格管理测试数据，包括用例的管理、测试数据录入、测试结果显示等等，这个需要封装一个Excel的类。
3、调用http接口采用java自带的的API
4、测试需要的将参数转化成字符串
5、通过预期结果和实际结果的对比，将实际结果和对比结果写入Excel用例中，这里封装了一个类
6、首次执行测试采用人工检查输出的是否正确，一旦正确写入Excel的期望结果中，如果发现错误手工修正为预期文件。
四、Excel表格设计
五、代码结构
