Hi everyone,

I just wanted to announce that Property-Based Testing with PropEr, Erlang, and Elixir is now finally out!

It is probably the friendliest introduction you can get to Property-Based Testing in this community, and also one of the best resource to bring you to a reasonably advanced level of skill.

If you’re interested in more details, please see any of:

• My blog post on the book: Property-Based Testing with PropEr, Erlang, and Elixir
• The Pragmatic Programmers newsletter: Property-Based Testing with PropEr, Erlang, and Elixir, in print

If you have previously read any of the beta copies, know that the final version now has both Erlang and Elixir code inline, at the same time (rather than Elixir in an appendix as in earlier beta copies). It was quite the fun challenge to make one book work for two languages, but I think you’ll find it works very well. If you only know either language, chances are you’ll feel comfortable reading both anyway before you’re halfway through.

And here’s also a twitter link in case any of you feels like making some noise on my behalf https://twitter.com/mononcqc/status/1083027123777036291

Thanks, and enjoy the read!

I was fortunate to be one of the beta readers for this book. I’m REALLY excited to see the finished product. Fred breaks these topics down in understandable ways and provides a lot of insight into how to think about property testing. There’s a real emphasis on ensuring that your tests are working to find the hidden bugs and not just generating random data.

Bought it with the coupon code of course! Now we just need a distributed systems in erlang/elixir book…
