Abstract

Architectural models, such as those described in the EAST-ADL language, represent convenient abstractions to reason about embedded software systems. To enjoy the fully-fledged advantages of reasoning, EAST-ADL models require a component-aware analysis framework that provide, ideally, both verification and model-based test-case generation capabilities. In this paper, we extend ViTAL, our recently developed tool-supported framework for model-checking EAST-ADL models in Uppaal Port, with automated model-based test-case generation for functional requirements criteria. To validate the actual system implementation and exercise the feasibility of the abstract test-cases, we also show how to generate Python test scripts, from the ViTAL generated abstract test-cases. The scripts define the concrete test-cases that are executable on the system implementation, within the Farkle testing environment. Tool interoperability between ViTAL and Farkle is ensured by implementing a corresponding interface, compliant with the Open Services for Lifecycle collaboration (OSLC) standard. We apply our methodology to validate the ABS function implementation of a Brake-by-Wire system prototype.
