软件错误定位效率可能受诸多因素影响,如测试用例优先级排序、测试用例构成、测试用例覆盖率及偶然正确性测试用例等.主要关注偶然正确性对怀疑度计算公式错误定位效率的影响.为此,提出一个基于函数单调性的理论分析框架来证明30个经典怀疑度计算公式受偶然正确性影响的程度.偶然正确性对怀疑度计算公式影响是有益的理论探索.%The efficiency of software fault localization may be affected by many factors,such as the prioritization of test case,the structure of test case,the coverage of test case and coincidental correctness test case etc. This paper focuses on the impact of the efficiency of calculation formula by coincidental correctness test cases. For this,we put forward a theoreti-cal analysis framework based on function monotonicity to prove the validity of 30 classical calculation formulas by coinci-dental correctness. It is a useful theoretical exploration that the efficiency of calculation formula is affected by coincidental correctness.
