摘　　要：针对传统软件可靠性验证测试方法均不考虑软件测试性可能会对验证测试用例数量产生影响的现状,提出一种引入测试有效性对软件可靠性验证测试最小量进行改进的方法.分析了软件测试性的定义及其对软件可靠性测试集合的影响,提出软件测试有效性的概念.比较了考虑测试有效性前后软件可靠性验证测试集合在数量上的差异,证明经典统计方法和无先验知识的Bayesian统计推断方法确定的均为假定测试有效性为零情况下的保守估计.提出结合测试有效性的验证测试量的量化表示模型和验证测试方案的改进方法,基于统计故障注入的原理,提出测试有效性的定量评估方法,最后通过示例给出定量评估过程和方法.To solve the problem that in the traditional software reliability demonstration testing（SRDT）,software testability was not considered as one of the possible influence factors on test effort,a method which introduced test efficiency to improve the quantity model of minimal sample size in SRDT was put forward.The definition of software testability and its effect on software reliability test suite were analyzed.The concept of test efficiency was proposed.The difference between the numbers of test cases with different test efficiency and whether efficiency is considered were compared.It was demonstrated in detail that the traditional method and the Bayesian method with no prior knowledge are all the conditions where the test efficiency equaled to zero,so both the methods gave the most conservative value.The improved method combined with the test efficiency was recommended.Based on the principle of statistical fault injection,the quantitative estimation method of test efficiency was proposed and the process and the estimation method were shown by a case study.
