Apply a dummy load and measure, but you have already proven the supply is out of spec, I wouldn't use it

I have an Arduino kit with a variety of resistors. Would I just take any resistor to use as a dummy load, or does it matter which resistor I use?
The PSU is rated at 2A 12v, so would I take 2A÷12²v? Should I look for a resistor that’s 0.0139ꭥ? My EE class was decades ago, mostly forgotten.
I also have a 12v LED lamp that I pulled from a dumped refrigerator which I could sacrifice.
I’m often in a situation of needed to repurpose dodgy PSUs with dodgy appliances, so I’d like to generally know how to do this.

You would want big thermal resisters, or something that doesn't care about the correct voltage like a big beefy motor
