1. A method of automating a diagnostic procedure executing on a computer system on a wellbore pump unit, comprising:
applying power to a unit controller comprising a processor, a non-transitory memory, at least one network device, a secondary storage device, and an input output device;
generating, by a diagnostic application, a diagnostic report file in the memory of the unit controller, wherein the diagnostic report file comprises a pass/fail status of a plurality of analog inputs, wherein the analog inputs comprise a plurality of analog sensors, and wherein the analog sensors comprises a plurality of pressure sensors, a plurality of valve position sensors, a plurality of tub level sensors, or combination thereof;
writing, by the diagnostic application, to the diagnostic report file a pass/fail status of the secondary storage device, wherein a write access is a passing status and a locked access is a failing status; and
displaying, by the diagnostic application, the pass/fail statuses in the diagnostic report file via the input output device; wherein the input output device comprises an interactive display, and wherein the pass/fail statuses comprise a color indicator, a text message, or combination thereof.
