Beer, Armin2023-04-192023-04-192009https://dl.gi.de/handle/20.500.12116/41250Testing of dependable event-based systems is very important to ensure that all requirements (including nonfunctional requirements such as reliability, availability, safety and security) are met, and the relevant standards are observed. In this paper we provide an overview of the state of the practice in testing dependable event-based systems and identify the challenges that have to be addressed in the future. We illustrate our findings by a case study for a transportation system. The most important topics for research and improvement are: (1) formal modeling techniques for domain experts, (2) smart monkey testing techniques for reliability testing (3) mutation analysis to reveal the defect-detection potential of test suites, and a (4) recommending tool for the selection of test-case design methods.enModel-based testingtest-case designtest automationrandomized testingmutation analysisText/Journal Article0720-8928
