Op :
It doesn't strike me as a good test, since I've seen several coils that
will pass your test, but won't run an engine.
At the very least you'll want to add a copy of the condenser to the
circuit. Firing a normal plug in free air is a poor test, since it's much
more difficult to fire a plug under compression. (Being wet with fuel, like
at startup, is even worse.) Cutting the plug's side terminal completely
off (so the spark jumps the 1/4" or so from the center to the shell) makes
a somewhat more realistic test, but as I recall still only takes about 5
kV.
I'd be thinking more along the lines of checking inductance and resistance
of both primary and secondary, plus insulation resistance and breakdown.
