Level Up Your Ruby on Rails Skills

About The Book

My goal with this book is to expose you to a new way of thinking about your Ruby on Rails applications and help you become 10x more confident in the code you write.

Here’s what you can expect to get out of it:

    How to plan and execute features for maximum productivity

    Instantly 10x your confidence in the code you write

    Improve your code even if you're not a senior developer yet

    How to defer refactoring for later

    How to make your code easy to change

What's Inside

Here’s the table of contents.

Table of Contents

I’ll never forget the day one of my former managers said:

Hey, I want you to manually click through all the pages of our website for every new feature you build, just to make sure we don’t introduce any new bugs.

That was the day I’ve decided I’ll get to the bottom of it, and set myself on a 10-year long journey that would eventually uncoverthe one thing that made all the code I wrote since 10x better.

This book is here to show you how to start thinking about, and start writing your first test in the behavior-driven way (Behavior-Driven Development).

I learn a lot faster when I see how the theory applies in practice. After reading this book, I am way more confident than I ever was in my ability to write fully-tested Ruby on Rails apps.
