Automatically Checking Conformance on Asynchronous Reactive Systems
share
Software testing is an important issue in software development process to ensure higher quality on the products. Formal methods has been promising on testing reactive systems, specially critical systems, where accuracy is mandatory since any fault can cause severe damage. Systems of this nature are characterized by receiving messages from the environment and producing outputs in response. One of the most challenges in model-based testing is the conformance checking of asynchronous reactive systems. The aim is to verify if an implementation is in compliance with its respective specification. In this work, we develop a practical tool to check conformance relation between reactive models using a more general theory based on regular languages. The approach, in fact, subsumes the classical conformance which is also available in our tool. In addition, we present some studies with different sceneries that are applied to practical tools with both notions of conformance.
