Abstract: The invention relates to a computer-implemented method for testing a driver assistance system for a vehicle, comprising simulating a scenario in which the vehicle is situated; operating the driver assistance system in an environment of the vehicle on the basis of the simulated scenario; observing a driving behavior of the driver assistance system in the environment of the vehicle; determining a driving situation resulting from the driving behavior of the driver assistance system in the environment of the vehicle; establishing a quality of the simulated scenario as a function of a criticality of the resulting driving situation; checking at least one termination condition; and changing the simulated scenario on the basis of the established quality until the at least one termination condition with respect to the quality is met. The invention also relates to a corresponding system.
