In this chapter, we have applied our theoretical knowledge of testing to the practical craft of constructing real, working, and clean test suites. We looked at some of the pitfalls that exist in doing so, and we highlighted the important qualities to strive for, such as clarity, intuitive naming, and following conventions.

In the next chapter, we will be looking into a variety of tools we can use to help us to write cleaner code, from linters to compilers, and beyond!
