AUTOMATIC TEST CASES GENERATION FROM UML ACTIVITY DIAGRAMS USING GRAPH TRANSFORMATION.

Recently Model-based test case generation is attracting more attention of researchers in software development. This is due to the fact that this leads to the early detection of faults reducing software development time and cost. UML 2.0 activity diagram is one of the behavioral models used for test case generation. In this paper we propose an approach based on graph transformation to generate test cases from UML 2.0 activity diagrams. To this end, we propose two graph grammars. The first one transforms a UML activity diagram to an intermediate representation while the second one generates test cases from the intermediate representation. An example illustrates the approach.
