Abstract: The invention relates to a method and to a device for testing a driver assistance system for a vehicle in a test environment. Traffic scenario descriptions are determined, which each characterize a certain traffic scenario and comprise at least one parameter, by means of which the traffic scenario in question can be adapted to constraints. The traffic scenario descriptions are stored in a traffic scenario file, in which the at least one parameter is stored in a predefined format. At least one traffic scenario description is selected on the basis of an input of a user and/or specified criteria. Furthermore, a test case is produced on the basis of the at least one selected traffic scenario description and at least one specified value for the at least one parameter.
