Abstract

Several outlines on model-driven approach for testing of embedded systems This paper is devoted to model-driven testing approaches in the context of embedded systems. The article discusses specifics of the embedded systems as well as specific testing approaches for them. As the testing objects of embedded systems next non-functional requirements were previously selected: task scheduling, time restrictions, synchronization, asynchronisms and reliability. Timing restrictions are selected for detailed analysis in model specification. For this purpose Time domain from UML profile for Schedulability, Performance and Time is presented and discussed. Testing model as destination model is specified using standardized UML Testing profile, which provides general purpose metamodel for such model definition. The main idea of the paper is to show general principles of the model-driven testing and to represent simplified example of testing of the one specific feature of the embedded system. Discussed model-driven testing approach is based on the model transformation, where the source model describes the feature of the system and the destination model is the test case model. Transformation rules in future works will provide test case generation using model of the system.
