Abstract:
Self-Adaptive Systems (SAS) are becoming more evident in our lives. By definition, these systems are supposed to adapt to changes in their context without human interference. It is essential that they are trusted to autonomously perform critical tasks in changing environmental conditions. That makes assuring their safety a vital task, and because of their complexity, a challenging one. In this work, our goal is to identify potential safety vulnerabilities of SAS at design time. We start by addressing safety requirements of SAS and transferring their natural language description to a guided template then to a formal description. After that, we aim to automatically generate adequate test cases. At the same time, we build the initial models of the system and with the help of a powerful simulator, we run the generated test cases against the system models. This way, we can validate the safety requirements of SAS at design time.
