This module will teach you unit testing and integration testing using tools such as Jest and Enzyme.

React App Testing

This module explores testing in React in detail. You will learn unit testing and integration testing using tools such as Jest and Enzyme. You will also learn about other tools such as ESlint, Prettier, Babel, Webpack, and Travis CI that add convenience to coding and testing.

Test-Driven Development with React


## Test-Driven development

Test-driven development (TDD) is the art of minimizing uncertainty, allowing you to feel confident about your code from the moment you write it. This is done by making a few assertions about that code beforehand. This groundwork sets up a short, satisfying feedback loop: as soon as you write your code, the tests light up green. Afterward, the tests remain in place, standing guard against regressions.

## What’s in this course

This is a course about React. But it’s not like any other course or book about React. This is a course about writing React code in a joyful way. You might learn a few new things about React, but that’s not my goal. My goal is to help you write better code and to have more fun doing it.



In the chapter **Test-Driven Development with Jest**, you’ll get a taste of test-driven development, a programming methodology that uses tests to create a feedback loop as you work. For the test framework, you’ll use the lightning-fast Jest library.
