1. A testing apparatus comprising:
a socket having a formation for removably holding an electronic device having an input terminal and a light emitter;
an input contact on the socket to connect to the input terminal on the electronic device to provide an input electric power through the input contact on the socket to the input terminal on the electronic device, the input electric power causing the light emitter to transmit light;
a temperature modification device on a first side of the socket, which, when operated changes temperature to cause a temperature differential between the temperature modification device and the electronic device and a transfer of heat between the temperature modification device and the electronic device to modify a temperature of the electronic device;
a heat sink on a side of the socket opposing the temperature modification device, the heat sink having a surface for absorbing the light, absorption of the light creating heat in the heat sink; and
a heat dissipation device thermally connected to the heat sink to remove the heat from the heat sink.
