后台服务端接口验证项目实例~~
前言:
在当前开放互联的大环境下,接口互通成了最最普通常见数据通讯与交互的一种方式;接口测试的重要性也是不言而喻,但却成了普通功能测试人员的一道屏障;特别是服务端的接口验证更是麻烦;这里抛砖引玉希望更多童鞋参与多多讨论。
场景&描述:
c1->s1->s2
s1 <-s2
协议:http
c端,发起c1(pay)请求,服务端处理完毕,通过s1接口把(pay)请求支付接口告诉指定s2服务地址;s2服务地址解析s1接口内容,正常返回SUCCESS,异常返回FAILURE;s1收到s2返回内容做对应业务处理。
接口消息格式:json,签名验签rsa标准算法,消息体url编码。
请求方式:post
测试对象:
s1接口
测试范围:
接口测试之常规测试维度,从宏观到微观一一细分拆借大概思路:消息发送方式、消息体是否为null、消息体格式是否正确、消息解密是否正确、消息体中json体key键检查(必填值是否缺省、缺省值是否存在、是否多多余key键)、消息体中json体values值检查(必填值检查是否缺省、缺省值是否存在、值类型检查,特别是数字类型的,比如交易金额啥的)。
接口测试之安全维度,ip黑白名单,消息体参数注入,摘要解密算法研究等。
1.消息发送方式
2.消息体是否为null和格式检查
3.json,key键必填字检查
4.json,values值检查
5.业务数据检查,比如收到SUCCESS检查。
6.其它
实现技术分析:
如果只要验证第5点,简单的只要模拟s2,最快速高效的方法,直接在tomcat下,新建一个工程,创建一个html文件,内容为SUCCESS或FAILURE;然后s1接口直接往这个地址发送就好(http协议)。
http协议,后台实现,最方便的还是java,也有python的,依赖的包太多,看个人条件选择;如果是soket套接字,建议与加密解密类语言保持一致比较好,因为解密太折腾人了,哎。
这里选择了一个java,servlet来实现。
再回头看s1接口,所以的参数都不是固定的,每次发生请求的参数都是动态的,这样的话,自己去实现这个servlet的时候,参数化的部分,就直接考虑连接db,这样就不需要考虑s1接口传入固定的值,动态的去db查询s1接口参数相关数据信息(特别是解密,与json,values值验证,和功能业务特性,每次填写固定参数值肯定不靠谱)。
