If the device is a simple gap breakdown type device, some sort of
improvised hi-pot tester might be a way to do it. Maybe something like an
auto ignition coil running off a lower than normal voltage, or a small
current limited HV transformer (like an oil burner ignition transformer or
neon sign transformer). Either way, you'd want to limit the discharge
energy in your tester.
You could verify that the device breaks down at the voltage it's supposed
to, and that it doesn't break down when it's not supposed to.
And, if the transient suppression device has a wear out mechanism (like
TranZorbs or various zinc oxide based TVSes) you'd not want to go too wild
with the tester.
