软件测试是软件工程中主要的研究领域之一，尤其是实时控制多任务软件的测试，尚无成熟而通用的工具。本文工作以机载航空电子通信与控制管理软件为背景和应用对象，探讨了嵌入式实时控制多任务软件的测试方法和实现技术；根据被测软件的特点，采用了路径遍历，对输入多数集按合法、边界、非法划分等价类的原则构造测试用例，设计了二度式测试用例生成程序、嵌入式测试驱动与记录程序等工具，使本文具有明显的特色，并对同类应用软件的测试工作，具有一定的参考价值 Software testing is one of the main areas of research in software engineering, especially the real-time control of multi-tasking software testing, there is no mature and common tools. Based on the characteristics of the software under test, this paper uses the path traversal, the input of the majority of the set According to the principle of legal, border and illegitimate division of equivalence classes, the test cases are constructed, and tools such as second-generation test case generation program, embedded test driver and recording program are designed to make the paper have obvious features and tests of similar applications Work, have a certain reference value
