切片在组件系统回归测试中的应用

Application of Slicing in Component-based System Regression Testing

在组件系统的回归测试中,为了确定修改所影响的部分,需要建立组件系统的依赖模型。组件系统具有高复用性和高复杂性,现有的依赖模型已经不适应描述组件系统,所以提出一种描述组件系统的层次依赖模型。通过对该模型中修改点的向前切片,得到修改所影响的部分,然后遍历该部分得到修改所影响的测试路径,进而有效地选择回归测试用例,提高了回归测试的效率。

In component-based system regression testing, the dependence model of component-based system should be built in order to confirm the part which will be affected by modify. Since high reusability and high complexity, the existing dependence models may not be applicable to component-based systems, a hierarchical dependence model is proposed to describe component-based. Through the forward slicing of modified points in the model, the modified and affected parts can be gotten, then traverse these parts and get affected testing path, thereby regression testing examples can be chosen effectively, the efficiency of regression testing can be improred.
