一种嵌入式软件的组合测试指标获取方案

为了获取组合测试中适应值函数所需要覆盖率、测试运行代价等信息，设计实现了基于嵌入式软件源代码插桩的指标获取方案。该方案使用交叉开发环境，完成了对源代码语法、词法分析，插桩库和插桩策略的制定，目标机／宿主机通讯方式设计，获得了语句覆盖率、分支覆盖率、运行时间、被测程序程序复杂度等关键指标，并以图表的方式提供统计结果，为组合测试设计适应值函数，进行测试用例约减提供了依据。

A Method of Combinatorial Testing for Indicators Based on Embedded System Software

In order to obtain coverage,test operation cost and other information needed by fitness function of combination test,the solution is designed based on embedded system software source code instrumentation.This solution uses cross-development environment,complete source code syntax analysis and lexical analysis,create instrumentation library,generate instrumentation strategy,design communication types between the target/host machine,get all sorts of indicators about statement coverage,branch coverage,running time,program complexity,give a diagram of the statistical results,provide the basis of reducing test case for fitness function designed by combination test.
