| 测试集自动生成工具的研究是协议一致性测试领域中比较活跃的一个分支，本文在对目前已有的各种测试集生成方法进行分析的基础上，提出了一种新的测试集自动生成方法并对它的实现ＴＵＧＥＮ作了介绍．ＴＵＧＥＮ基于一种称为ＥＢＥ的形式模型，ＥＢＥ模型只对协议的外部行为进行描述，而且可以从协议的Ｅｓｔｅｌｌｅ或ＬＯＴＯＳ描述中转化得到．ＴＵＧＥＮ以协议的ＥＢＥ－ＮＦ描述作为输入，使用我们新提出的一套测试事例生成策略，最后产生出ＴＴＣＮ．ＭＰ格式的测试集．我们用Ｘ．２５ＬＡＰＢ协议的ＥＢＥ－ＮＦ描述作为例子，对ＴＵＧＥＮ |
| 英文摘要: |
| This paper presents a tool called TUGEN which is used for automatic test suite derivation from formal protocol specification. TUGEN is based on a formal model called EBE (External Behavior Expression) which can be obtained from formal protocol specification in either Estelle of LOTOS. This model specifies only the external behavior of a protocol in terms of the input/output sequences and their logical (function and predicate) relations. Based on the EBE specification of a protocol, a test sequence derivation method is used to identify associations between inputs and outputs through the interaction paths and their I/O subpaths, then generic test cases specified in TTCN (Tree and Tabular Combined Notation) can be generated from these I/O subpaths. Comparison of test cases generated from this tool and those in ISO/IEC DIS 8882 part 2 for X. 25 LAPB protocol shows that the resulting set of test cases of TUGEN is concise and effective. It is our belief that TUGEN can be a powerful utility for protocol test suite generation. |
