Abstract: A test device for a fluidic pump device (10), which can be driven by a drive device and of which the pump rotational speed that leads to a defined fluid volumetric flow on the output side (12) of the pump device (10) is known, is characterized in that the fluid volumetric flow is conducted at least temporarily via a pressure influencing device (22) which, during operation of the pump device (10), brings about a pressure drop, by way of the decrease of which an evaluation device (32) makes a statement about a reduced functional capability of the pump device (10) possible.
