摘要

经常有测试组件或模块的需求,这些组件或模块接受各种参数,这些参数需要以特定的方式组合起来,就像用自然语言指定的约束所指示的那样。扩展上下文无关语法(Extended Context Free grammar, ECFG)适合对上述测试需求进行建模。构建一个工具,它接受ECFG形式的测试设计,并自动生成测试数据或脚本。为了在ECFG中提供一个用户友好的界面来表达测试设计,该工具提供了一个使用数据流图的可视化形式。报告了一些案例研究来证明该方法的好处。

Model based testing using an Extended Context Free Grammar
There exists a frequent requirement to test components or modules that accept various parameters which need to be combined in specific ways, as dictated by constraints specified in a natural language. Extended Context Free Grammars (ECFG) are suitable for modeling the above test requirements. A tool is built that accepts a test design in the form of an ECFG and generates test data or scripts automatically. With the objective of providing a user-friendly interface for expressing test designs in ECFG, a visual formalism using data-flow graphs is provided by the tool. Some case studies are reported to demonstrate the benefits of the approach.
