test-check

Is there a good way to provide some initialization for a property when used with the clojure.test integration? For example, I have this code:
(defspec my-gen-test
100
(kafka/with-driver [d (make-driver {})]
(prop/for-all [record (my-record-gen)]
(kafka/pipe-input d record))))
with-driver is basically the same as with-open (i.e. it will close a resource after the form's body completes). The problem I'm running into is the property check doesn't appear to block until it's completed so the driver opens and then closes pretty quickly. Is there a way to work around this? Currently thinking to just make my own defspec that can handle this sort of thing.kenny 2019-08-20T19:32:00.006700Z
I could write my own quick-check fn like this:
(defn quick-check
[num-tests property & opts]
(tc-test/assert-check
(apply tc/quick-check num-tests property opts)))

@kenny you it to be opened/closed just once for the whole test run, across many trials?
kenny 2019-08-20T19:34:28.007900Z
Yes. Open at the beginning, close at the end.

It should run through all the properties using the same driver.

If you did it in a fixture and bound a dynamic var, would that be good enough?
kenny 2019-08-20T19:36:22.009800Z
Yes but fixtures are icky. They either run with each deftest or only once. Neither of those choices are a good fit.

Oh right
2019-08-20T19:38:21.010400Z
Yeah I don't think there are any super clean options

That quick-check wrapper fn should work for now
