基于分类树的雷达软件测试用例设计

摘要

Owing to larger and larger scale of software size, it is less and less feasible to test every functional unit of modern radar software by using common combinatorial testing techniques in engineering. Aiming at solving defi-ciency of a large amount of redundant test cases generated by using the classification tree method ( CTM) designing test cases, the orthogonal experimental design method based on case set generated by CTM is used to simplify and optimize the testing so as to improve testing efficiency. The experimental results show that optimization of testing case based on orthogonal experimental test designing method can be used to reduce redundant test cases effectively and save test source and cost. It possesses applicable value in engineering.%现代雷达软件测试由于软件规模越来越大，利用常规的组合覆盖方法测试各功能单元工程上越来越不现实。文章针对分类树方法设计测试用例产生大量冗余测试用例的缺陷，提出了在分类树方法生成的用例集基础上，利用正交试验设计法对其进行精简优化，以提高测试效率。实验结果表明，基于正交试验设计法的测试用例优化，可以有效减少冗余测试用例，节省测试资源和成本，具有一定的工程应用价值。
