Testing is the cornerstone of building high-quality software, but it doesn't have to slow you down. Rather, testing can actually help you deliver new features quicker by eliminating debugging time, minimizing re-work, and reducing the cost of changing existing code.

So, how do you get started and continue practicing test-driven development when the pressure is on? A common mistake is to focus on the tools. And in the Rails community there's certainly no shortage of good testing tools. But the tools only get you so far. The long-term value is in learning the practices and techniques of test-driven development. That's what this course is all about: Building high-quality applications the red-green-refactor way!

In this course you'll learn test-driven development by actually doing it through a series of guided hands-on exercises. You'll come away from this course in the testing mindset with a solid foundation of the practices.
You'll finally get TDD and have the experience to make it stick.
