Generative testing (aka property testing), popularized by the Haskell library QuickCheck, is a technique of:

- specifying invariant laws your code expects to exhibit
- generating random inputs to verify the laws
- simplifying failures to find error boundaries
- providing replay mechanisms for easy debugging

In this BrooklynJS talk, I show the motivations for and basics of property testing in JavaScript, via the library fast-check. Slides are posted at
