The paper presents a novel technique to create the test cases from UML models. In this technique, the UML diagrams such as Use Case Diagram, Class Diagram & Sequence Diagram of any application are considered for creating the test cases. A graph is created to store the necessary information that can be extracted from these diagrams & data dictionary expressed in OCL for the same application. The graph is then scanned to generate the test cases that are suitable for system testing.
