A short practical guide you can apply right away

If you are a software developer, you have probably heard of test-driven development (TDD). Some people even insist that you can’t write good quality software without it!

We will not argue about whether or not TDD is essential. What this short booklet will do is show you how to apply TDD in real-life projects. By the time you finish reading it, you will also understand that, at the very least, TDD can be very useful. Also, it’s not as complicated as many people think. Once you do it a few times, you will see that it’s actually easy.

There are many approaches to doing TDD. There are also many opinions on what TDD is and isn’t. In this booklet, we will not discuss any of this. We will just focus on the TDD approach that works. This booklet distills all the philosophy, arguments, etc. into a small number of fundamental principles you can learn easily and apply right away.

There are many good TDD books out there, such as “Test-Driven Development by Example” by Kent Beck. However, such a book will take you hours to read. I know you are busy. You may not have a few hours to spare. And this is precisely why I created this booklet for you.

The information provided here will take you less than an hour to read. And you can apply it right away. Then, if you still want to expand your theoretical knowledge of TDD, you can still read a book about it.

After all, TDD is not complicated at all. Let me show you exactly why.

Here is a list of the take-away skills this booklet will give you:
