A test system for a medical system that has a central control unit to control medical system components dependent on received operating commands, has an interface for setting up a data connection to the central control unit, a data storage, and a transmission device that provides a sequence of date packets that correspond to operating commands for controlling the system components, coded for the central control unit of the medical system, according to the specification of a test file readout from the data storage, and for monitored transfer of the sequence of data packets to the central control unit. The present test system allows automated function tests of medical systems to be reproducibly implemented without effort by personnel.
