In this chapter, we took a break from TDD and introduced many tools and frameworks that will be used for code demonstrations in the rest of the chapters. We set up everything from version control, virtual machines, building tools, and IDEs, until we reached frameworks that are commonly used as today's testing tools.

We are big proponents of the open source movement. Following this spirit, we made a special effort to select free tools and frameworks in every category.

Now that we have set up all the tools that we will need, in the next chapter, we will go deeper into TDD, starting with the Red-Green-Refactor procedure-TDD's cornerstone.
