performing a specification of the at least one test and/or the at least one simulation, the specification including at least one specification part,

selecting parameter values and/or setting values; and

assigning concrete parameter values and/or setting values by the specification for the at least one test and/or the at least one simulation, the parameter values and/or setting values are selected manually or automatically,

wherein already stored specification parts are selected manually and/or automatically and integrated into the specification, and

wherein the at least one specification part is provided with meta-information indicating a relationship between the at least one specification part and an element of an operational design domain.

2 . The computer-implemented method according to claim 1 , wherein the method further comprises at least one test of a device for anthe at least partially autonomous guidance of a transport vehicle, wherein the transport vehicle comprises at least one ego vehicle and/or fellow vehicles, and wherein the ego vehicle is a vehicle with a system under test and a fellow vehicle is any other vehicle.

3 . The computer-implemented method according to claim 1 , wherein the parameter values comprise:

scenery parameters comprising at least one of the features: a number of and/or a width of a lane and/or curves and/or road restrictions and/or an ambient temperature; and/or
