In this section, we concluded the setup of our test machine. You also learned the location of the CLI terminal for the majority of operating systems. Also, we installed all of the necessary components that will allow us to follow all of the exercises in this book.

We also took the time to understand why our test classes are named the way they are. We covered the file and class naming conventions, and you also understand how Ruby does namespacing and declares inheritance.

We are now ready to start writing our tests!
