Abstract: Model-based GUI testing (MBGT) approaches are efficient since their test cases can be generated automatically.Employing multilevel morphology model (MMM) in MBGT allows testers to explore the morphological differen-ces of GUI model,therefore,it can increase the fault detection effectiveness.However,MMM can only be extended as a whole to the increasing level of MMM,and the model becomes more and more complex and harder to process.In this paper,we proposed a MMM segmentation approach which is based on event classification,and a relevant test case gene-ration strategy which employs BFS and CPP algorithm.This approach enables MMM to focus on the important parts of model,and meanwhile,reduces the number and length of test cases,makes MMM more agile and efficient.The result of the experiment indicates that the segmented MMM has almost the same fault detection effectiveness as its original mo-del,and will become more efficient if the model level increases.
