In this Vue 3 tutorial, we learn how to compare two images of an application with snapshot testing. We cover how to write and compare snapshots with Jest, how to update an older snapshot and how to use mocked data in a test.

We cover the following topics:
1. Lesson Project
2. What is Snapshot Testing
3. How to write a snapshot test with Jest
4. How to update a snapshot
5. How to use mocked data in a snapshot test

Note that this tutorial is for the Vue 3 Options API (which is similar to Vue 2). We later move on to the Composition API and then the Script Setup (3.2 update)
