摘　　要：增量法是应用于集成测试的方法,合适的增量集成策略能够降低测试成本、保障测试的充分性、提高测试效率。针对目前嵌入式软件集成测试增量方法不明确、对于函数调用关系验证不充分等问题,通过参考集成测试相关国家标准并结合嵌入式软件的特点进行深入分析,提出一种新的集成测试序列生成方法。该方法从集成测试函数调用关系的充分性入手,按照以"层间集成"为主、"层内关键系数集成"为辅的设计思路,将嵌入式软件中的函数基于节点层和关键系数以集成的先后顺序划分,得到经粗调和微调后的增量集成序列。该方法能简单、高效地解决集成测试增量集成问题,具备工程实践应用意义。Incremental Integration strategy is applied to integration testing and appropriate incremental Integration strategy could be used to reduce high-cost,ensure sufficiency and increase efficiency to a large extent.Aimed to solving problems of insufficiency of function calling testing and unclear of increasing methods,a novel method of node-layer net for generating integration testing sequence by deeply analyzing National Military Standard and characteristic of embedded software is presented.By combining outer-layer and inner-layer factors to generate integration testing sequence,the sufficiency of interface testing between different function could be guaranteed.In conclusion,the method can solve the problems of incremental integration in integration test simply and efficiently,and has engineering practice and application significance.
