It is focusing on PropEr and PropCheck, and this book provides explanation for both Erlang and Elixir, but quoting the book…
The concepts should not be hard to carry over from framework to framework in any case.
StreamData is exclusive to Elixir.

The book is divided into 3 parts:
- the basics
- stateless properties in practice
- stateful properties
Parts 1 should be useful regardless of the tool used, as it covers more foundational knowledge (thinking in properties, etc.). Part 2 should still be useful if using StreamData, but you’ll obviously have to adapt the code. Part 3 cannot be used with StreamData, as StreamData doesn’t provide state checking (StreamData: data generation and property testing for Elixir - #12 by josevalim)
You can probably get a good grasp of how helpful the book would be to you by reading http://propertesting.com which seems to cover most of part 1 in the book (it’s by the same author), although code samples are only in Erlang.
Hope this helps!

As others have said, you should be able to apply a lot of the thinking with stream data although some of the operations just aren’t supported right now so I’d suggest going through the book using propcheck. We use both at work. StreamData for very basic generation of data and Proper for when we need more robust testing, model checking, etc.

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

Thanks, and enjoy the read!

The Philly Elixir Group will be using Property-Based Testing with PropEr, Erlang, and Elixir for their next online book club, starting Jan 28th. If anyone outside Philly would like to join us, there are very welcome!
