Line regulation: A variable power supply.
Load regulation: A variable electronic load.
At least a good meter to monitor output voltage. If you have two, then use the second to monitor the output current. Otherwise use the readings from the E-load.
Simple as that. If the instruments have computer connectivity, via USB or HPIB or whatever, one can write a simple script to take a lot of datapoints and plot the results
These are really simple simulations and you don't have to rely on someone giving you the test bench for that. If you are a beginner then start from the beginning. Line and load regulations are the beginning.
