Acknowledgments

After writing Refactoring: Ruby Edition, I swore I’d never write another book. Book writing is unquestionably a labor of love, and I wouldn’t be able to do it without the support of my many friends in the industry.

• Martin Fowler: Thank you for allowing me to reference and reuse content from Refactoring. It’s still my favorite technical book of all time.
• Obie Fernandez: Thank you for the nudge to use leanpub; it was crucial for making this project happen.
• Michael Feathers: Honestly, I just liked the way Working Effectively with Unit Tests sounded. I never considered that anyone would associate this book with a book as universally loved as Working Effectively with Legacy Code. Nonetheless, I’ll do my best to deliver a book that is worthy of being on the same shelf as Working Effectively with Legacy Code. Thank you very much for your blessing.
• Original Reviewers: There’s no question this book is significantly better due to the feedback I got from those who originally volunteered to provide feedback. Thank you Graham Nash, John Hume, Pat Farley, & Steve McLarnon.

Additionally, I’ve been happily surprised by the support I’ve gotten from people who purchased the early edition on leanpub and promptly provided feedback. Many thanks - Allan Clarke, Corey Haines, Derek Reeve, J. B. Rainsberger, Jake McCrary, Josh Graham, Kent Spillner, & Steve Vinoski.

I’m sure there are others who I’ve forgotten; I apologize and offer my thanks.
