An Approach to Generate Test Cases from Sequence Diagram

Testing is an important area of software engineering. There are various types of testing methodologies followed in various stages of Software Development Life Cycle (SDLC). We are proposed a novel approach for generating test cases from UML sequence diagram. Our approach consists of transforming sequence diagram in to sequence diagram graph and generating test cases from SDG. The sequence diagram is prepared based on the Use Case diagram in which describes the overall view of the system. The traceability between the models is provided by using Relational Definition Language.
