Effective Testing with RSpec 3 （英文版）(序言)

Early praise for Effective Testing with RSpec 3

Ruby embraces the old Lisp idea that you should “build up a language” to address your problem, and RSpec carries this approach into the world of testing. But RSpec is a big toolbox, and in order to harness its full power you need a guide. This is that guide: the bridge you need to take you from writing tests, to expressing your design requirements in code.

➤ Avdi Grimm Author of Confident Ruby and Exceptional Ruby and Head Chef, RubyTapas

Effective Testing with RSpec 3 does a great job of explaining both the main features of RSpec as well as its lesser known, powerful, and often overlooked features. It’s an essential resource for Rubyists looking to learn RSpec, or for those who use it every day. I’ve already started using it regularly as a resource.

➤ Noel Rappin Author of Rails 4 Test Prescriptions and Director of Development, Table XI

Myron and Ian have written the essential “missing” manual for modern RSpec, connecting all the latest best practices for TDD and BDD. If you were having trouble mastering modern testing with RSpec, this book will sort you out.

➤ Sam Joseph Co-instructor on the BerkeleyX Agile Development using Ruby on Rails MOOC and co-founder, AgileVentures Charity

Myron has been the driving force behind RSpec development for years. He is an expert on testing practices and getting the most out of the RSpec suite. His care and attention to detail are impeccable, and it shows in both the codebase and this book.

➤ Xavier Shay RSpec core team member and Payments Engineering Lead, Square

Having worked with Myron for many years on the RSpec core team, I’m very pleased to see Effective Testing with RSpec 3. This book contains everything you need to learn not only how RSpec works, but how to test effectively with the framework. If you’re working with RSpec on a daily basis and looking to get better at working with the framework, I could not recommend this book more heartily. ➤ Sam Phippen

The exercises are illustrative and challenging. The final chapter on test doubles really synthesizes the best way to use these tools. You’ll write far more readable and robust specs after reading this book, especially when interfacing with the shifting sands of third-party APIs.

➤ Nigel Lowry Company Director and Principal Consultant, Lemmata

Effective Testing with RSpec 3 is well worth a read: it is much more than a technical reference and will make you a better developer by teaching you how to write more expressive, robust, and maintainable tests.
