In the Ruby on Rails community it’s expected that developers know how to write tests.
If you aren’t in the habit of writing tests you can feel like an imposter.
Barriers to Learning Ruby Testing
You know you “should” be testing but it’s not clear how to start. You might have questions like:
- How do I get started with testing? What exactly do I test?
- How do I pick a testing framework?
- How do I find books and tutorials that are actually up-to-date?
These barriers are real. That’s part of the reason why so many developers struggle to write tests.
Imagine If You Could…
Imagine that you already had all the knowledge you needed to confidently write tests with little effort.
Imagine if you:
- Easily wrote a test for every feature you wrote without even having to use Google or a book
- Deployed features to production with confidence that everything works (and old code won’t break)
- Received praise in code reviews about how well-tested your code is
- Welcomed questions about TDD in job interviews as a chance to demonstrate your knowledge
Introducing: Intro to Ruby Testing
Intro to Ruby Testing is an interactive, hands-on course that will help you get over the barriers to testing and put you on the path to being a confident Ruby tester.
This course will:
- Show you what kinds of features to test
- Show you evergreen testing concepts – so you don’t have to worry about the material being out of date
- Walk you through many concrete testing examples
- Introduce you to testing with just Ruby and ActiveRecord, no Rails – meaning you can strip away the many confusing details of testing in Rails
- Get you “over the hump” with learning testing and equip you with the confidence to continue your testing journey on your own
What Do You Get If You Sign Up?
This course is not about reading or watching video, it’s about you the student writing actual working tests.

It took me many years to get fully confident with testing. It doesn’t have to take you that long though. My hope is that I can share with you what I’ve learned through slow, painful experience so you don’t have to make the same mistakes.
