This paper designed an altimeter-testing system based on software engineering. Firstly, the need of multi-threaded test of altimeter was raised up; Secondly, the needed hardware environment was analyzed if the virtual instrument techonogy was used in measurement system; Thirdly, the testing process of two different signals and two types of sensitivity was toally designed based on multithreaded testing) Forthly, the total timing of testing process based on UML language was designed; Lastly, the human testing interface based on CVI9. 0 was designed and the testing process was programmed. This scheme optimized the test system development process, halfed testing time, improved the testing accuracy to decimeter and improved the reliability of the system.%利用软件工程的思想对某型弹载高度表测试系统进行研制；首先提出了高度表多线程测试的需求,分析了测试系统采用虚拟仪器技术所必需的硬件环境,采用多线程测试的方法将并行的两个高度信号和不同高度灵敏度的测试流程进行了总体设计,运用UML语言设计了测试流程的总体时序,最后通过CVI9.0设计了人性化的测试面板并对测试流程进行了编程实现；该测试方案优化了测试系统研发流程,将测试时间缩短到原来的一半,将测试精度提高到分米级,提高了系统的可维护性.
