A stationary test device for a missile includes a retaining device for an avionics testpiece of the missile, where the retaining device enables a movement of the avionics testpiece in three rotational degrees of freedom, and a display device configured to display information on the missile surroundings, where the display device is configured to be moved inside a virtual plane by a translational carriage system. The display device can be detected by the avionics testpiece if the avionics testpiece is disposed on the retaining device. A mobile test device for the missile includes a flight platform, a carrier device mounted on the flight platform, for an avionics testpiece of the missile, wherein the carrier device enables a movement of the avionics testpiece in three rotational degrees of freedom, and a control module, where the control module is configured to control the flight platform for taking off on a specified reference trajectory, control the carrier device for orientation of the avionics testpiece, and store navigation data generated by the avionics testpiece. Finally, a test system for the missile includes the stationary test device and the mobile test device.
