Ah, I missed it! Lazytest sounds interesting. Will the video be posted?
I'll post it as soon as I can get the recording. I missed it too, so looking forward to watching.
If y'all are interested in LazyTest, check out #releases today: new version of LazyTest, new version of Polylith external test runner that supports LazyTest (alongside clojure.test and Expectations), and a fork of Cognitect's test-runner that adds LazyTest support!
