From TDD to PBT via Kotest — Garth says "I’ve been a big fan of Property Based Testing for a number of years, based on my experiences with ScalaCheck. It’s always been an annoyance that Kotlin did not support this testing style, at least to the same extent. There was some functionality in Kotest (formerly KotlinTest), but it paled in comparison to what was available in Scala, F# and Python."
