# Summary

That's a wrap everyone, we're now finished with all the chapters of the book.

Although we weren't able to get 100% coverage of our Bookstore API, we have learned how to write automated tests in each layer of our application. You'll be able to use this new-found knowledge going forward and have much more confidence in your code when building new RESTful API endpoints.

To end off at a high note, why don't we all run our tests one more time and appreciate this automated work of beauty.
