(1) 本文提出的技术主要关注对原有测试用例集的缩减,未考虑系统变化对测试用例选择的影响,故缩减
后的测试用例集不能发现未实现服务调用关系中的缺陷,实验中是通过直接沿用新增测试用例弥补
这一覆盖性.我们将研究日志变化与微服务系统变化之间的关系,进而将日志变化作为参考因素,对
新增的测试用例进行选择;
(2) 本文提及的日志挖掘技术是非增量式的,每一轮迭代都要重复扫描整个日志内容,这在实际应用过程
中会造成一定的计算资源开销.我们将结合增量式日志挖掘方法改进本文所提技术,并探讨模式挖掘
的可复用工作模式,一次挖掘、多处使用,进一步提升技术性能;
(3) 本文所提技术在本质上是通过挖掘日志信息获得用户使用模式,进而将其作为测试用例缩减的参考
因素.事实上,该技术并不依赖于 API 网关层,对于其他架构特征,例如服务网格等,只要能获得服务调
用日志数据,便可应用本技术.下一步将尝试在不同领域、不同架构模式的系统中应用本技术,采用更
多的项目素材进行工程实证研究.
