摘要

本文介绍了一种用构件分析法分析软件可靠性的方法。它介绍了执行软件组件可靠性分析的6个步骤。分析可以在测试软件之前开始，并且可以帮助选择测试策略。它在软件组件级使用扩展执行时间(EET)可靠性增长模型。本文描述了如何从软件组件的特征和测试用例和操作使用对软件组件的压力特征来估计模型参数。测试用例运行的顺序用于组合组件模型，以得到测试期间软件的复合可靠性增长模型。本文通过一个例子说明了基于操作概要选择测试用例与基于测试用例的统一覆盖选择测试用例对可靠性增长的影响;并将软件组件增量交付给系统测试。本文将所描述的方法与目前用于分析测试过程中软件可靠性增长的其他方法进行了比较。可以使用商业数据分析程序进行分析。

Software component reliability analysis

This paper describes an approach to analyzing software reliability using component analysis. It walks through a 6-step procedure for performing software component reliability analysis. The analysis can begin prior to testing the software and can help in selecting testing strategies. It uses the Extended Execution Time (EET) reliability growth model at the software component level. The paper describes how to estimate model parameters from characteristics of the software components and characteristics of how test cases and operational usage stress the software components. The order in which test cases are run is used in combining component models to arrive at a composite reliability growth model of the software for the testing period. The paper walks through an example illustrating the effects on reliability growth of: selecting test cases based on an operational profile versus selecting them based on uniform coverage of test cases; and incremental delivery of software components to system test. The paper contrasts the described approach to other approaches currently used to analyze software reliability growth during testing. The analysis can be done using commercial data analysis programs.
