### Source excerpt

Today marks the official release release of Working Effectively with Unit Tests. The book is available in various formats: DRM free pdf, epub, & mobi (Kindle) at http://leanpub.com/wewut Softcover at http://amzn.com/1503242706 Kindle edition at http://amzn.com/B00QS2HXUO I'm very happy with the final version. Michael Feathers wrote a great foreword. I incorporated feedback from dozens of people - some that have been friends for years, and some that I'd never previously met. I can't say enough great things about http://leanpub.com, and I highly recommend it for getting an idea out there and making it easy to get fast feedback. As far as the softcover edition, I had offers from a few major publishers, but in the end none of them would allow me to continue to sell on leanpub at the same time. I strongly considered caving to the demands of the major publishers, but ultimately the ability to create a high quality softcover and make it available on Amazon was too tempting to pass up. The feedback has been almost universally positive - the reviews are quite solid on goodreads (http://review.wewut.com). I believe the book provides specific, concise direction for effective Unit Testing, and I hope it helps increase the quality of the unit tests found in the wild. If you'd like to try before you buy, there's a sample available in pdf format or on the web. © Jay Fields - www.jayfields.com
