## What it is
Course material for Kent C. Dodds' TestingJavaScript.com course on testing React components with Jest and React Testing Library. It contains a series of exercise files covering rendering, mocking, accessibility, TDD, and testing hooks, portals, and Redux-connected components.

## Use cases
- learn how to test React components with Jest and React Testing Library
- find examples of mocking HTTP requests in React component tests
- practice test-driven development of a React form
- learn to test accessibility with jest-axe
- see how to test custom hooks, portals, and error boundaries
- follow along with the TestingJavaScript.com video course

## When to choose
- you are taking or reviewing the TestingJavaScript.com React testing course
- you want hands-on exercise material for React Testing Library patterns
- you learn best by working through guided, incremental test examples

## When to avoid
- you need a production-ready testing utility or library rather than educational exercises
- you want up-to-date examples for the latest React or Testing Library versions, as the material dates from around 2022
- you are not using Jest and React Testing Library in your project
