After the summer break 🌴, it's time to go back to #OpenSource and spend some time onto the maintenance of fast-check 🤫
Lots of upcoming #features in the pipe: new arbitrary for strings able to base its generated values onto examples provided by the user, support for non-serializable values on our worker-based extension, better integration with @vitest and start to pile stuff for a new major version of the library (without huge breaking changes).

Why is #PropertyBased #Testing key in development cycles? Because it can detect nasty #bugs or #regressions happening only under certain circumstances.
The technique just revealed a regression in fast-check 3.6.x, now patched in 3.6.3.
Release note: https://github.com/dubzzz/fast-check/releases/tag/v3.6.3

CW: How to Property Based against 'designing data structures'?
Just started to extend my set of examples showing how to leverage #PropertyBased to #JavaScript algorithms on "stacks and queues". On this topic, most of my tests adopt #model #based #testing as it mostly deals with designing new #data #structure, so it fits well.
See https://github.com/dubzzz/cracking-pbt/tree/main/stacks-and-queues 👀

People often wonder if #PropertyBased #Testing is really applicable. I started a demo example showing how to leverage #FastCheck against exercises coming from Cracking the Coding Interview in #JavaScript at https://github.com/dubzzz/cracking-pbt
More demos to come (race conditions..)
