You might also test the regulation as the load changes. When I was really bored (recovering from back surgery) I measured the ripple suppression of a regulator and pass transistor arrangement. I don't know if that would be a basic test but it is a test that you could run.
An often overlooked test is "dynamic stability", where the load is suddenly applied and then removed. You are looking for "overshoot" and "damping". A power supply is after all a feedback control system, so it should be tested as one.
I once built a load tester for qualifying our power supplies when I worked for a defense contractor. It used a power transistor as the load element, and I could just dial up the load current by adjusting the base bias. It replaced the keluge of switches and power reisistors we were previously using.
I was able to disqualify many power supply designs with it Wish I still had the schematic. It was a very simple concept and design though.
I'll check what I have. I faintly remember a design I made a while ago for an adjustable load between some milliWatt and a few hundred Watt. (Requires turbo cooling though)
If you have a switch mode power supply-booster type
boosting 2v to 5v
the battery input is from 2v to Vout
-lets say you use a 6V battery................(but Vout is 5V not 6V, so what is going to happen if you use 6V???)
OK i know THATS GOING TO KILL THE PURPOSE of using a booster.
BUT a switch mode power supply(SMPS) IS MORE efficient than using a 9V battery with a LM7805 to give you 5V output for the micro controller........................
The battery on the SMPS will last longer............ + The 9V battery and LM7805 is bulky & the battery power fades fast

Technically, it was never stated that this was a regulated supply, so there wouldn’t be a feedback loop. But if it was regulated, “transient response” testing is only an indicator of “conditional stability”. Generating some bode plots would be the real indicator of loop stability.
