Abstract
The Unified Modeling Language (UML) is gaining wide acceptance in industry as the new de facto visual modeling language and as such it is being used within Siemens to model large, complex new product lines. As a result, we are extending our existing UML-based approaches to component and system validation to address the needs of product line validation. In this paper, we will focus on describing the extensions made to our system testing approach in which Activity Diagrams that form the basis for the test specification are annotated with variation points and conformance tests are then automatically generated to validate each product variant. We are also implementing these extensions as part of our Test Development Environment for UML (TDE/UML) automated test generation technology, which is currently integrated with the IBM/Rational Rose UML modeling tool and coupled with test execution tools, such as a graphical capture/replay tool. This paper provides an outline of our existing UML-based approach to system validation, but focuses on how we supplement the existing UML diagrams with information concerning the variation points for product-line validation.
