摘　　要：设计了一种面向功能的嵌入式系统多串口测试软件,该设计从面向功能的角度出发,以功能需求为起点,功能实现为终点,能够精确地进行故障定位,缩短了检测故障时间;根据输入与输出的功能关系,采用人工输入与自动生成2种测试用例生成方案,并将测试用例随机进行排列组合,提高了测试用例覆盖率;采用多线程管理技术,实现了1台PC同时管理控制多台下位机。本设计已经被用于实验室现行项目中,运行的成效证明了设计的可行性。In order to solve the problem that the traditional software testing is time-consuming, costly and difficult, this paper designs the function-oriented approach for embedded system as a promising approach to devise automated test- data generators. Hence,the design can precisely locate the fault and performance statements. According to the functional relationship between the inputting and outputting,there are two kinds of generation schemes of the testing case,one is manually inputting and the other is automatically generating, and in order to improve the coverage of testing case, the design makes them permutated and combinative randomly. What＇s more, the design uses the muhithreading test-data management technology to realize a PC to control many lower machines. This design has been used for the ongoing projects in the laboratory,and the effectiveness of the running proved the feasibility of the design.
