1. A test bench for testing a distance sensor operating with electromagnetic waves, wherein the distance sensor to be tested includes at least one sensor radiating element for radiating a transmission signal and a sensor receiving element for receiving a reflection signal, the test bench comprising:
a receptacle for holding the distance sensor to be tested;
an at least partially movable connecting member in the radiation area of a distance sensor held in the receptacle;
a test bench receiving element held in the connecting member for receiving a transmission signal radiated by the sensor radiating element; and
a test bench radiating element held in the connecting member for radiating a test bench transmitting signal as a simulated reflection signal;
wherein the test bench receiving element and the test bench radiating element are arranged together in a movable part of the connecting member.
