一种基于功能构件的Web应用建模与测试方法

Approach to Modeling and Testing Web Applications Based on Functional Components

Web应用与传统程序有着很大差别,后者的一些建模和测试方法不能完全适用于前者。提出了一种有效的对Web应用测试的方法。按功能将Web应用划分成若干个功能构件,把Web应用看成是功能构件的集合,并在功能上将其对应到实际的Web应用模块。用有向图表示功能构件的结构关系,用FSM表示功能构件的行为关系,用FSM的复合表示功能构件的交互。提出了完整执行序列覆盖、构件完整执行序列覆盖两个测试准则,根据这些准则生成测试用例集。为支持所提出的方法,设计了一个测试用例生成的工具原型。

There are great differences between Web applications and the traditional programs. The modeling and testing methods of the traditional programs can not be fully fit for Web applications. An approach to generating test cases effectively was presented. A Web application was divided into a set of functional components, each of which corresponded to an actual Web application module. A directed graph is employed to represent the structural relationship among the functional components, an FSM was used to represent their behavioral relationship, and the FSM composition was used to represent their interactions. In testing, two test criteria which are complete executing sequence coverage and component complete executing sequence coverage were proposed. To satisfy these two criteria respectively, different test sets were generated. Additionally, a test case generation prototype was designed for the approach proposed.
