軟件測試是軟件質量保證的重要手段。本文構建了基于軟件測試工具Testbed/RTInsight 針對PC104 系統的實時嵌入式軟件測試環境。以求方程根的c 程序為例進行PC104 系統的軟件動態測試，最后給出了動態覆蓋率及性能分析的實驗結果。性能分析能記錄分析程序中每個函數的最大運行時間，最小運行時間，總的運行時間，以及運次數。
關鍵詞：軟件測試；嵌入式軟件；軟件質量；軟件性能分析
Abstract: Software testing is an important method to assure software quality. We contruct the
embedding 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.
