Abstract
The automotive modernizations in the past decades are dominated by new software-based functions. A validation of these functions is always required for ensuring the safety of the vehicles. Several studies show the effectiveness of design-based methodologies for performing testing and evaluation of vehicular system functionalities. Along with the advancement of automated driving technologies, the demand for simulation-based assistance of such vehicles is increasing. For the simulations, the modelling of the observation sensors plays an indispensable role. State-of-the-art studies and research investigations elucidates an ever-increasing requirement of efficiency of the test paths. The elementary structure of the modelling is also delineated here, and a viewpoint for future requirements on it is given. Prime path coverage and edge-pair coverage when combined with prefix graph algorithm generates least number of yet effective test cases which can traverse all the states in less time. Other approaches such as node coverage or edge pair coverage also yields good results but the test path requirements are very large.
