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.

I've sharpened that skill over the years to the point that I now teach it to Ruby teams all over the world.

And because not everyone can hire me to coach them 1-on-1, this book is thedistilled version of the knowledge I provide in my coaching sessions, at a fraction of the cost. It shows you how to start thinking about and writing your first test in a behavior-driven way (Behavior-Driven Development).
