Posts above neglect to mention the starter motor needs a mount to rotate the engine. That means either a partial or full gearbox housing, and the required real estate for this gets a little tricky the way most engine stands are configured.
As suggested, the engine should be be close to normal operating temperature for accurate compression and cylinder leakage results, but while one shouldn't necessarily compare cold test results with factory specs, it's close enough for a very rough estimate.
Cylinder leakage testing requires the test cylinder to be positioned @ TDC end of compression. That task is the same with the engine installed or on an engine stand. Accessing the plugs and fishing loose spark plugs that fall out of the socket is easier on a stand, but that's quite minor. Preventing the crank from rotating is easier on a stand (lock flywheel in place), but for more accurate results, the engine should be at normal operating temperature.
