摘　　要：为实现C语言开发的嵌入式软件自动路径覆盖测试,提出了基本路径覆盖(Z路径优化)测试探针插桩技术。初始化时确定探针算法、分配内存空间,插桩策略解决了插桩位置及方法,采用消息队列机制完成测试数据采集,使用模式匹配删除探针恢复现场。通过模拟测试XSBase 255嵌入式系统上的C语言计算器模块(callbacks.c),从覆盖率看出取得了一定的效果,为测试和维护工作提供了底层数据支持。In order to realize roboticized path coverage testing for C language,the instrumentation technology in basic path coverage testing（Z path optimization） is researched.The probe arithmetic at the time of initialization is designed,and then distributed EMS memory.The instrumentation location and method are solved by the instrumentation strategy.The message queue is used to finish data collection.Finally,the pattern matching is used to delete probe.The coverage results showed that the research achieved a certain effect through simulation tests XSBase 255 embedded system C-calculator module（callbacks.c）,which supported the underlying data for testing and the maintenance work.
