So, is it too much of a weight penalty to put a capsule-lauch emergency booster on the satellite capsule for such a test?
If the static test is satisfactory, then you unbolt and remove the safety rocket before the real launch. Or leave it on the capsule to recover the satellite if the main rocket goes off at the real launch.
Or, after a few seconds of flight, use the thrust from the emergency rocket to add a few lbs of thrust while in flight. Then eject the empty safety rocket.
