Abstract: A testing design decision analysis algorithm based on test importance was proposed for software test design strategy optimization. According to Analytic Hierarchy Process (AHP) theory, the algorithm was used to solve the problem of test importance comparison and analysis through combining quantitative and qualitative methods. Then the targets including optimization of test design strategies, reasonable distribution of test resources, effectively finding software defects can be achieved.

摘要： 针对软件测试设计策略优化问题，提出一种基于测试重要度的测试设计决策分析算法。该方法依据测试有效性原则，采用层次分析理论，通过定量和定性相结合的方法，解决软件测试过程中测试重要度比较和分析问题，完成对软件测试设计工作的重点或优先级的决策分析，优化测试设计策略，进而合理地分配测试资源，有效发现软件存在的缺陷，提高软件测试的效率。
