摘要
根据已有的投资回报(ROI)分析模型,结合COCOMO度量结果,在充分考虑回归测试时测试程序维护成本基础上,提出一种软件自动测试风险判别和规避模型。模型首先提出平均维护代价因子概念并计算其阈值,然后对每次维护代价因子进行正态分析,通过正态分布判别自动测试的风险性,最后利用敏感性分析给出风险规避的策略。模型为整个自动测试过程提供动态指导和正确的决策,避免风险发生。
A model of risk judgment and avoidance for the software test automation, based on the Return On Investment（ROI）model and COCOMO measurement results, is presented. The maintenance cost of regression test is also taken into account. The model first proposes a concept of mean maintenance cost factor and calculates its threshold, and then analyzes the each time maintenance cost factor by normal method. According to normal distribution, we can obtain the possibility for the test automation risk occurrence. At last a strategy for the risk avoidance is proposed by the sensitivity analysis. The model provides dynamic guidance and correct method for the whole software test automation in order to avoid risk occurrence.
