1. A testing apparatus, comprising:
eyewear having a processor and a frame supporting an optical assembly;
a sensor coupled to a surface portion of the eyewear proximate to the processor of the eyewear to measure a temperature of the surface portion;
a server configured to provide instructions to the processor; and
a testing device coupled to the surface portion and configured to measure the temperature of the surface portion using the sensor during execution of the instructions by the processor to determine the temperature as a function of the executed instructions, wherein the testing device is configured to determine a utilization of the processor during execution of the instructions, and determine a single process processor utilization of a selected thread during execution of the instructions to determine the temperature.
