There are still a bunch of little things I want to tweak in the 3rd edition, but this draft should give you a good idea of what the final book will look like. Comments and feedback are welcome.

For someone who has been coding in Rails for years but hasn't ever done the testing side of things, would you recommend working through your book or looking at other resources to get up to speed?

As someone who is very familiar with testing from a JavaScript perspective yet is just getting started with rails, I have to really applaud the testing approach in the latest draft edition. It is very well done as well as a marvelous introduction.

I'd guess the 3rd edition of the Ruby on Rails Tutorial would be an excellent place to start for learning the basics of testing.

Michael Hartl's Rails Tutorial was the best book I have read for learning Rails. I picked it up during university and quickly moved onto my own projects and from there into a career in web development. Without a doubt this book is the biggest contributor to me finding my first contracting job and I recommend it to anyone who shows interest in learning how to develop for the web. I will definitely be purchasing the third edition when it comes out, purely to show support for such a great resource.

Thanks Michael, I hope the third edition's launch goes well.

Michael, I'm currently working through the second edition - it's fantastic. I'm on chapter 5 but I'd like to switch over to the third edition. Is it worth restarting? Again thanks for such a great resource.

Its worth switching over if only for his use of minitest over RSpec

Yes, I think restarting is worth the trouble.

Hello - will the new 3rd edition come with an updated screencast series? How will you price the screencast + ebook bundle?

Yes, there will be a new screencast series. I haven't decided yet on the pricing, but it will generally be in line with previous editions.

I wonder if you should just bump into 4th version so people don't think it goes with Rails 3.

Going through learn ruby the hard way, excited this is finished in perfect timing.
