To break that out:
JWS: 36 = 12 JWS "alg" values * 3 header protection levels (some/all/none)
JWE: 288 = 16 "alg" values * 6 "enc" values * 3 header protection levels
Plus 2 for multi-signer and multi-recipient

So it seems I mis-counted, and there are actually 326 tests.  (I tried to
be thorough!)

If you tried to do something similar with CMS or IKE, I think the
combinatorics would be similar.  The TLS cipher suite registry is of
comparable size, and less organized (flat list instead of separate
parameters).
