For it to be considered a test of the nuclear weapon, does the nuke have to actually go off, or would a test of the other aspects of the nuclear weapon count (eg a missile test with no payload but that could carry a nuke)?

@Nat usually, nuclear test implies actual detonation, but clarification from OP would be nice.

@Nat Definitely must include a nuclear detonation.

Interesting spikes on this market today.
