Earlier this year I was asked to evaluate a book concept about Spock framework. Taking into account that I am a big fan of this library I was extremely happy to see that measures were taken to create a book focused on this particular topic. Hopefully the book will boost even further the popularity of Spock. As always high interest of a product is the best motivation for its authors to continue its development. Few months later, I am given a possibility to read the early edition of this book and as well was asked for a review.
