Visual Regression Testing with Jest

This is a walkthrough of how to set up Visual Regression Testing with Jest for an application created with create-react-app.

The following walkthrough uses React as an example, but the approach should work for any modern frontend library! I assume it can be used with Angular, Vue, Cycle.js and more.

This gist walks you through a create-react-app application as an example of how to set up Visual Regression Testing in Jest using libraries I wrote recently which enable this: jsdom-screenshot, jest-transform-css and jest-transform-file.

Application structure

General

1. Application has tree structure with folders for each "feature"
2. Feature folders are named with lowerCamelCase → myComponentDashboard
3. Feature can contain any number of components and nested features
4. Components are named using UpperCamelCase → MyWidgetComponent.vue
5. Component can have translation .yml file named correspondingly → MyWidgetComponent.yml
6. If component requires more than 2 files: .vue and .yml file - folder is created with the same name → MyWidgetComponent
