Testing is the most dominating validation activity used by industry today, and there is an
urgent need for improving its effectiveness, both with respect to the time and resources for …

Abstract Model-based testing relies on abstract behavior models for test case generation.
These models are abstractions, ie, simplifications. For deterministic reactive systems, test …

In this paper we review how the Uppaal Tool Suite served in industrial projects and was both
driven and improved by them throughout the last 20 years. We show how the need of …

We study the generation of test cases for nondeterministic real-time systems. We define a
class of Determinizable Timed Automata (DTA), in order to specify the system under test …

We denote by qa−−→ q that (q, a, q)∈→. The main differences between a labelled transition
system and a finite-state automaton are that the set of states Q and the alphabet L (and …

In this article, a collection of major problems to be solved for automated testing of embedded
hard real-time systems is discussed. It is indicated which solutions are available …

This paper introduces a new technique for testing that a distributed real-time system satisfies
a formal timed automata specification. It outlines how to write test specifications in the …
