软件测试是软件质量保证的重要手段。本文构建了基于软件测试工具Testbed/RTInsight 针对PC104 系统的实时嵌入式软件测试环境。以求方程根的c 程序为例进行PC104 系统的软件动态测试，最后给出了动态覆盖率及性能分析的实验结果。性能分析能记录分析程序中每个函数的最大运行时间，最小运行时间，总的运行时间，以及运次数。关键词：软件测试；嵌入式软件；软件质量；软件性能分析Abstract: Software testing is an important method to assure software quality. We contruct theembedding real-time software testing environment for PC104 system based on Testbed/RTInsight testing tool.We take the C program of equation root as example,and implement the software testing.The outcome of the experiment,that is ,dynamic coverage and performance analysis, is presented.At the same time, for each software function we can obtain the maximum executive time, the minimum executive time,the total executive time and the executive counts.Key words: Software testing; embedded software; software quality；software performanceanalysis
