For anyone who either doesn’t subscribe to updates from Leanpub, or is still on the fence about buying my book about learning Rails testing through RSpec, I just wanted to pass along that I pushed an update this evening with the following updates:
== to eq throughout the book to mirror best practice in RSpec expectations.expect() syntax (chapter 3).:message factory (chapter 5).In addition, Leanpub is now accepting credit card transactions–so those of you who in the past couldn’t use PayPal can now buy a copy. Still only nine American bucks.
Join me on a thought experiment: How does my time-tested approach to testing Ruby on Rails applications apply to the tools we get from the framework? Whether you're new to Rails testing, or curious about the default testing stack, Testing Rails from Scratch gives you a pragmatic, end-to-end introduction to test-driven development. Covers Rails 8.1 and Ruby 4.0. Early release now available for sale on Leanpub!
