About the Book
Ruby on Rails offers powerful tools to test your software's features out of the box. But how do you use them to ship code with confidence? And how do you ensure that AI-generated code works as intended?
Testing Rails from Scratch is a practical guide to testing Rails applications at every level, using (mostly) tools that the framework includes by default. You'll learn to test the way I did, by starting with simple building blocks and expanding into complex tests covering broad swaths of your code. Learn to test with confidence!
Testing Rails from Scratch covers Ruby on Rails 8.1 and Ruby 4.0.

Earn $8 on a $10 Purchase, and $16 on a $20 Purchase
We pay 80% royalties on purchases of $7.99 or more, and 80% royalties minus a 50 cent flat fee on purchases between $0.99 and $7.98. You earn $8 on a $10 sale, and $16 on a $20 sale. So, if we sell 5000 non-refunded copies of your book for $20, you'll earn $80,000.
(Yes, some authors have already earned much more than that on Leanpub.)
In fact, authors have earned over $15 million writing, publishing and selling on Leanpub.
