Abstract
UML diagrams are important design and modeling artifacts. These diagrams can also be used to generate test cases. We present a novel test case generation method that is based on dynamic slicing of UML activity diagrams. We use flow dependence graph (FDG) of an activity diagram to generate dynamic slices. Dynamic slices are created using an edge marking method. Slices are constructed corresponding to each conditional predicate on activity edges and test cases are automatically generated with respect to each slice. Our generated test cases satisfy path coverage criterion. Our test data generation scheme is automatic and the test data is generated considering the slice condition. We have implemented our approach to realize a prototype tool.
