Test case generation using activity diagram and sequence diagram

Abstract

In this paper, we present an approach to generate test cases by usingtogether the UML activity diagram and the sequence diagram. Our approach consists of transforming the sequence diagram into a graph called Sequence Graph (SG) and transforming the activity diagram to the Activity Graph (AG). Henceforth, System Graph (SYG) is formed by integrating the two graphs i.e. SG and AG. The SYG is then traversed to form the test cases. We have used DFS (Depth First Search) method as a Graph Optimization technique .for traversing the SYG.It was observed that the test cases obtained from this method is not only exhaustive but also optimized. The test case thus generated is suitable for system testing and detect the operational, interact and, scenario faults.Our approach is also capable of handling the state explosion problem in case of concurrent systems. © 2013 Springer.
