摘　　要：针对专家系统规则库的软件测试和评价是保证专家系统质量与可靠性的重要环节。基于数据流的结构化测试技术,提出了一种规则库执行流图RBEF,用于描述规则库中不同规则之间相互连结、制约关系,进而给出了一组规则库覆盖度量准则和测试用例的设计方法,最后讨论了一个已实现并付诸于应用的基于RBEF的软件测试工具ESRTS。Software testing and evaluation for rule-base of expert system is an important part for ensuring quality and reliability of expert system. Motivated by structural testing techniques based on data flow analysis, a RBEF was proposed, which showed the coupling and restriction relationship of rules. Furthermore, rule-base coverage metrics criteria and test case design methods were put forward. And finally an implemented software testing tool ESRTS based on RBEF was analyzed.
