and also this thread

Testing Elixir (PragProg)

Hey everyone, I am not sure on where to buy this book or not. I would personally like to know what the book considers a Unit test, which I assume is explained in chapter “Defining the Unit in Unit Test”. This would help me understand if this book is more London or Detroit oriented (which school of TDD it preaches). Has anyone bought this already? What does the book say?
