Hi @mchean,
My favorite Phoenix book is Programming Phoenix >= 1.4. Elixir books are Programming Elixir >= 1.6 and Elixir in Action, 2nd ed when starting out and I’m really enjoying Designing Elixir Systems with OTP for more advanced architectural patterns. Finally Programming Ecto is excellent.
In my earlier post (since the thread relates to TDD specifically) I also recommended Mastering Phoenix Framework since @shankardevy uses TDD on every iteration including E2E testing with Hound. Other books cover testing but I haven’t found any that focus on it as comprehensively as he does. Hope this helps!
