Changes for the Second Edition
A lot has changed in the Rails testing world over the past five years, even if
the general principles stayed more or less the same. This book has been
substantially rewritten from its first edition, with almost no part of the book
unchanged. Here’s a more complete list of changes. (Not all of these changes
will be in the early beta versions.)
• All tools have been upgraded to their latest versions: Rails 4.1.x, Minitest
5.3.x, RSpec 3, and so on.
• The opening tutorial was completely re-written. It’s an all new example
which provides, I hope, a more gentle introduction to testing in Rails.
