did some googling but only found this, which does seem to show at least one other person ran into this 🙂 https://github.com/AdamFrey/cljs-test-check-warning-example

heya all

how are people using test.check with async code?

is there any pretty obvious way to do it?

I saw @gfredericks POC on https://github.com/clojure/test.check/commit/f90ee794dbe4dc766d91f9daa2160e8a8b0853be

Huh. Does that work? I don't remember it 🙃

In any case there's nothing more official than that

ok, now I know

I was asking because @wilkerlucio actually did something similar to what you did, but with core.async channels

https://github.com/clojure/test.check/compare/master...wilkerlucio:async-check

wilker and I were using it for test at http://roamresearch.com but now needed to extract it away from the official test.check

so I was wondering if there was something around already that we should be using

It's possible there are other libraries. But I'd say this is the most severe hole in test.check at the moment. That POC could be usable if the cljs.test details are worked out, and if it doesn't hurt perf for synchronous jvm use

what are the cljs.test details?

just "how should this be used from cljs.test?"; ideally it'd be similar or same as on the jvm e.g., can defspec work?

hm I see...

I was kinda focused on cljs so that didn't really come to mind

there I'd just use an async deftest

It might be easy. I just didn't know much about cljs testing when I made that commit

ok, will think about it some

thank you for the insight on this
