【摘要】 自动生成测试序列始终是软件工程中一项极为困难的工作．国际标准化组织（ＩＳＯ）一直致力于协议一致性测试方法与形式化描述技术的研究．本文讨论了基于形式化描述的协议测试序列生成方法中的问题，特别是提出了“部分Ｔ序列叠加算法”对使用ＵＩＯ序列生成测试序列的方法做了进一步改进，大大减少了测试开销．更多还原

【Abstract】 The selection of appropriate test cases is an important issue for conformance testing of protocol implementations as well as in software engineering. This paper describes an optimization method for reducing the length of protocol conformance test sequences by"Partial T sequences overlapping method", which are obtained using UIO sequences.This method provides a logical link between T method and UIO method.It is shown that test sequences generated by this method can shorter 10%-60% than those generated by other methods employing UIO sequences in an example.更多还原
