Get comfortable with Rails testing
Testing is an important part of developing quality software. They are lots of opinions on how we should test Rails applications, but I think the answer is a bit nuanced. This book takes a pragmatic and unopinionated stance on testing web applications with Rails well-integrated testing stack.

Minitest & fixtures
Like with other things in the Rails Doctrine, Rails offers us Minitest and fixtures on its ‘omasake’ menu. And delicious menu it is! Minitest is easy to learn, read and understand without a complex DSL. Fixtures provides no fuss super fast testing data at your fingertips. What’s not to like?
Why this book?
There are plenty of good testing books out there, but you’ll have hard time finding an up-to-date book on testing Rails applications with the Rails default stack. Looks like the Rails community put Minitest and fixtures on the sideline in favour of RSpec and factories, but not anymore!
Who is this for?
I expect you to be already familiar with Rails as this is not a tutorial of building the whole application from scratch. I go straight down to talking about tests with varied examples. Previous knowledge of Minitest is not required.
What you’ll get?
You’ll get PDF and ePUB copies. The ePUB is tested on Apple Books and Kindle.
What about updates?
The book comes with lifetime updates.
