Is this a good idea when motor swapping?

I always test a motor (less the tranny) prior completing the full engine bay assembly. I test it with oil, only, mainly to determine engine health and oil leaks. You can buy a mini serpentine belt that slips over the crank pulley, tensioner, and alternator, only; obviously, you'll want to bypass the water pump, AC compressor, and PS pump.
Be sure to bolt up the flywheel using all the FW bolts; otherwise, oil will leak through the bolt holes in the crank defeating the purpose of the test.
You can run it a minute or two without coolant from a cold start, and that should be enough time to check oil pressure and any oil leaks. Once the motor is off, you can perform a compression and/or leak-down test.
