In this chapter, we have been looking at the Ten Commandments for writing good test suites. Following these Ten Commandments is hard. It is a struggle to work with the limitations in order to produce even better test suites that provide more value than they cost. But if you follow these commandments, you will be falling into the pit of success, making it a struggle to fail.

This concludes the end of this book. We have been looking into how you can benefit from F# when writing high-quality code that is covered by tests. I have been showing how functional programming plays into the unit testing role and how we can benefit from the paradigm in order to make our test suites stronger and more robust.

I hope that you have enjoyed reading this book as much as I have enjoyed writing it, and I hope that you found it valuable in your path to great test suites and bug-free applications.
