1. A foreign object emulation device for testing foreign object detection of a wireless power device having at least one wireless power coil, wherein the foreign object emulation device is in operative communication with a processing means, wherein the foreign object emulation device comprises:
a main body being arranged with at least one emulated object,
a sensor unit comprising at least one temperature sensor configured to transmit temperature data to the processing means, wherein the temperature data is indicative of the temperature of the at least one emulated object, and wherein the processing means is configured to receive the temperature data, and at least based on said temperature data instruct the drive unit to move the at least one emulated object and/or the wireless power device, and
means for causing a controlled relative movement between the at least one emulated object and the wireless power device being tested, wherein the means for causing controlled relative movement is in operative communication with a drive unit.
