['1. A testing device (30; 50) for testing a wireless power transmitter device (20) having at least one transmitter coil (24a-f), wherein the testing device (30; 50) comprises at least one wireless power receiver coil (34) and wherein the testing device (30; 50) is in operative communication with a processing means (42; 52) having an associated memory (44; 54), wherein the testing device (30; 50) is configured to: receive a power signal applied by the wireless power transmitter device (20); transmit a first packet, wherein the first packet is a signal strength packet, to the wireless power transmitter device (20) in response to receiving said power signal; transmit a second packet to the wireless power transmitter device (20) when the wireless power transmitter device (20) continues to transmit the power signal to the testing device (30; 50) in response to receiving the signal strength packet, characterized in that  the processing means (42; 52) is configured to: store the signal strength packet or store signal strength value(s) thereof in the memory (44; 54) if the transmitter device (20), in response to said signal strength packet, continues to transmit the power signal to the testing device (30; 50); or else, if the wireless power transmitter device (20) aborts the power signal during or before the second packet is completely transmitted, disregard the signal strength packet or value(s) thereof.', '6. The testing device as defined in any of claims 1 to 4, wherein the processing means (42) and its associated memory (44) are arranged in a host device (40) being in communication with the testing device (30).']
