You can hook up a vacuum source to the booster inlet port and see if it holds a vacuum. Other than that you really need to put it on to see if it fails under pedal pressure.

I have had a couple that held a vacuum until the pedal was pressed then they dumped all the vacuum and did not work to slow the car down. Pedal just went to the floor with no effect.
