The Symbolic Analysis Laboratory (SAL) is a suite of tools for analysis of state transition systems. Tools supported include a simula-tor and four temporal logic model checkers. The common input language to these tools was originally developed with translation from other languages , both programming and specification languages, in mind. It is, therefore, a(More)
SUMMARY The Java programming language supports concurrency. Concurrent programs are harder to verify than their sequential counterparts due to their inherent non-determinism and a number of specific concurrency problems, such as interference and deadlock. In previous work, we have developed the ConAn testing tool for the testing of concurrent Java(More)
The refinement calculus is a well-established theory for formal development of imperative program code and is supported by a number of automated tools. Via a detailed case study, this article shows how refinement theory and tool support can be extended for a program with real-time constraints. The approach adapts a timed variant of the refinement calculus(More)
Starting with a UML specification that captures the underlying functionality of some given Java-based concurrent system, we describe a systematic way to construct, from this specification, test sequences for validating an implementation of the system. The approach is to first extend the specification to create UML state machines that directly address those(More)
Testing SCADA (Supervisory Control And Data Acquisition) near real-time systems is challenging, as it involves complex interactions and the simulation of the supervised and controlled environment. Model-driven testing techniques can help to achieve clarity about the inner workings of the system and facilitate test construction, but these models are(More)
