Deriving Combinatorial Test Design Model from UML Activity Diagram

Combinatorial test design model consists of parameters, values and the associated constraints. This model is the input for test generators. In this paper we present a rule based approach for deriving combinatorial test design model from UML activity diagrams resulting from requirement analysis. We have explored this approach on few sample cases. Our initial results suggest that this automated approach augmented with manual review and refinement step can make the test design task less effort intensive and more effective.
