The unreasonable interference of concurrent threads makes the testing activity for concurrent systems a difficult task. Test case explosion is the major problem in concurrency testing and make an interruption in systematic testing of concurrent systems. In this paper, the authors propose an approach of generating test cases from combinational UML models. In their approach Activity Diagram (AD) and Sequence Diagram (SD) are used to model a system. The AD has converted into a graph called Activity Graph (AG) and SD into a graph called Sequence Graph (SG). Finally AG and SG are combined to form a graph called Activity Sequence Graph (ASG).
