基于组合测试的V＆V单元测试用例设计研究

摘要

The special characteristics of nuclear safety-critical application software include complex digital logic diagrams, and a great number of inputs, etc. Combinatorial testing aims to detect faults caused by interactions among factors with a small number of test cases. Referring to features of nuclear safety-critical application software, and based on traditional combinatorial testing, this paper proposed a multi-level combinatorial test method. This way was proved to reduce the number of test cases effectively, increase the efficiency of software testing, and improve the ability of detecting potential errors. It is worthy of a further research.%核电安全级应用软件的特点包括：复杂的数字逻辑结构,输入变量多等。组合测试旨在使用较少的测试用例,有效地检查出由各因素之间的作用而产生的缺陷。针对核电安全级应用软件输入变量多的特点,结合传统组合测试算法,提出一种基于分级组合测试思想的单元测试用例设计方法。实践表明该方法能够大幅度减少测试用例数量,有效提升测试效率,更快速地发现潜在软件缺陷,是一种值得继续深入研究的可行方法。
