1. An apparatus, comprising:
energy harvesting circuitry of an energy harvested device;
at least one processor of the energy harvested device to be powered at least in part by the energy harvesting circuitry; and
testing circuitry coupled to the at least one processor, wherein the testing circuitry comprises a battery and a test controller, wherein the test controller is powered at least in part via the battery, wherein the test controller automatically initiates testing of one or more workloads to be executed at least in part by the at least one processor under one or more particular energy scenarios, and wherein the testing circuitry further comprises a real time clock powered at least in part via the battery, wherein the testing circuitry becomes energized by the battery a specified period of time after deployment as determined at least in part via the real time clock;
wherein the energy harvesting circuitry, the at least one processor and the testing circuitry are implemented on a particular integrated circuit die.
