Chapter 7: Testing and Auditing Your Site

In this chapter, we will learn about what unit testing is, why it's useful, and how to start unit testing your Gatsby site. We will then learn how we can use Git hooks to trigger your unit tests and other commands when running common Git commands. Following this, we will investigate how we can measure core web vitals to understand how well our Gatsby site's page experience is performing, both in lab and field environments. By the end of this chapter, you should feel comfortable that you can analyze how well a Gatsby site is working locally by using unit tests and looking at web vitals when it is out there on the web.

In this chapter, we will cover the following topics:
