testcheck-js

simple-check eventually became an official Clojure Contrib project, test.check[0]. In recent years it has been ported to Clojurescript (even allowing Javascript applications to benefit from property-based testing[1]) as well as seeing useful integrations into structural-typing and validation libraries such as Schema[2] and Spec[3]. Many thanks to Reid for introducing the Clojure world to QuickCheck! We gained an indispensable tool to leverage as Clojurians (notably in Onyx[4]).

In case anyone is interested, TestCheck.js [0] is a JavaScript implementation of QuickCheck. When I had last checked it out I vaguely remember thinking it was still too young to pick up. But looking over the APIs right now, it looks like its been steadily improving. I think my first introduction to property based testing was this video [1] from F# for fun and profit. The speaker does a great job at presenting the topic in a way that's clear and approachable. Ff you prefer text over video, on the same post there's links to other blog posts which cover the same material. [0] https://github.com/leebyron/testcheck-js [1] https://fsharpforfunandprofit.com/pbt/
