Abstract: In order to reduce the cost and improve the efficiency of regression testing, this paper presents a repression testing method based on the analysis of the change of domain. The change types are described in detail. And the corresponding domain analysis strategy is put forward for each type. The results show that the method has good technical guidance and is easy to use, which improves the adequacy of the regression testing and further ensures the quality of the test.

Key words: regression testing, change types, domain analysis
