Derivation of System Integration Tests from Design Models in UML

As model-driven software development is increasingly used, techniques to derive additional information from design models are rapidly explored. One kind of these additional information is test information. In this paper we present an approach of deriving a certain kind of test information for system integration test from a given design model. For a given domain with a generic behavioral model our approach has the ability to generate system integration tests that are specific for any design model of the same domain. The system integration tests are generated as sequence diagrams, where every diagram represents one specific test case for a concrete design model. The approach is of general use since all models are UML 2 models. We illustrate our approach using a case study for a simplified MOST audio system.
