I’m happy to share the first release of Everyday Rails Testing with RSpec, updated for 2024. If you ever purchased a copy through Leanpub, you can download this one for free, along with all future updates.
This release includes the following:
I still have many chapters to update, along with some planned new content to cover testing concepts I didn’t include in past versions, and augmenting test-driven development with generative AI.
If you still need the complete (albeit very outdated) Rails 5.1 version, I’ve made the download freely available, along with sample source code for this version. See the all-new book resource page for details.
Thank you as always for your support, patience, and kindness as I’ve worked on these updates. Watch for the next batch of updates in the coming weeks!
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!
