Testing Rails from Scratch

Description

Welcome to the Leanpub Launch video for Testing Rails from Scratch: A practical, (mostly) out-of-the-box approach to test-driven development in Ruby on Rails https://leanpub.com/everydayrails-testing-from-scratch by Aaron Sumner! 0:00 Aaron introduces himself and gives an overview of the book and who it's for 0:47 How Aaron learned test-driven development by breaking it into small, incremental steps 1:33 How blogging about TDD led to Aaron's first LeanPub book on RSpec 2:21 How vibe coding and AI-generated code inspired revisiting Rails' default testing stack 3:06 Current state of the book: first three chapters launched, more chapters planned for summer 3:54 How writing the new book is changing Aaron's long-held views on testing in general 4:42 Len reflects on Aaron's first book as a canonical LeanPub success story 5:27 Why testing still matters in the age of AI and vibe coding 6:18 The difference between tests that verify intent versus tests that just confirm what the code already does 7:09 Why human understanding of testing concepts remains an invaluable part of the software workflow 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.
