Contents don’t mention the subject of Elixir testing. Are you sure there’s nothing to add about the how, when, where, and what of Elixir testing?
Thanks for your question. I do think testing is important, so I’d like to address this.
I’ll tell you a secret. I started writing this book in a full-on TDD style. I quickly realized that the testing was taking over the focus of the book, and I had to re-write what I had already done without tests to get it back on track.
There will be an appendix pointing readers toward resources for testing. And to give you a forthright answer, I don’t think I would have anything groundbreaking to add to what is already available.
I finished chapter 3 and felt a need to understand the code I had written following the book so far. I started writing unit tests.
My tests are here: https://github.com/arvindhiman/islands_engine
I finished the first cut of Coordinate in chapter 2 and was feeling the need to get a handle on Elixir unit tests.
