摘　　要：嵌入式软件测试中,代码覆盖率测试和内存检测通过给程序源代码插桩,在程序动态运行的过程中搜集测试数据;但是这种插桩无法获取进程每次运行的时间。基于进程切换的内核task hook插桩,是通过对Linux2.6操作系统内核进行分析,建立了进程监控的插桩点选取,获取进程生命周期中的时间相关的指标,最终实现程序的任务性能测试。In the software testing, source code instrumentation can be used test code coverage and memory detect, and then collecting testing data during the program dynamic running, but the way can not used to getting process run time. The kernel task hook instrumentation based on process switch, which is though analyze the kernel of Linux 2.6 then establish instrumentation point for process scout, for achieving timing relevant index of process during it＇s life periods, then implement task performance testing for program.
