you can mix both to limit the awful (g/fmap rand-uuid (g/return nil)) I think

but it's still bad

i see. so if you aren’t using the generator’s api test.check can’t work its magic?

test check needs to control all sources of entropy

(if you want the other features of generators eg strinking and repetition to work)

@lwhorton no, test.check uses the same api. the issue here is using external sources of randomness

gen/uuid already exists, is that not ok for you?

oh, i didn’t notice that. i will check it out. my real gotchya was that i have an instance? check against cljs.core/UUID and wasn’t sure how to make that happen randomly.

The builtin uuid generator should only generate instances of that type
