Reactive Model-Based Testing of Cyclic Systems
Year: 2026
Type: article
Abstract: There is extensive literature on automated test generation using reactive design models, where control is determined by events. In contrast, the (idealised) simulation paradigm defines control through cycles dictated by the passage of time. Within each cycle, inputs are read and processed, and outputs are provided, all instantaneously, and afterwards time progresses. To exercise a simulation using tests generated from a reactive design model requires changes to the tests to take into account this paradigm shift. This article focuses on automation of the necessary changes and of the use of the resulting tests in a simulation campaign. Based on a notion of conformance that establishes whether a simulation is correct with respect to a reactive design, we (1) identify the reactive tests that are meaningful; (2) define a process to convert those tests; (3) provide an algorithm to execute those tests and (4) prove soundness and completeness of our approach. Our work is described in the context of the RoboStar framework for model-based development of control software for robotics applications, and its process algebraic semantics. The testing approach we propose here represents a significant advancement in the current testing practices within the field of robotics, where simulations are widely used.
