Model-based test generation is an approach to generate test cases based on a formal model. Although test generation methods have long existed, its timed counterpart is still a new field. In addition, most of the proposed solutions suffer from combinatory explosion which continues to limit their applicability in practice. Accordingly, it explains why there are so few automatic formal methods for testing generation, for both time and untimed systems. This book presents an overview about models, specification languages and test generation approches adressed to timed systems. In addition, it...
