Jest

Jest is a JavaScript testing framework designed to ensure correctness of any JavaScript codebase. It allows you to write tests with an approachable, familiar and feature-rich API that gives you results quickly.

Jest is well-documented, requires little configuration and can be extended to match your requirements. For more information on Jest checkout its official documentation. https://jestjs.io/docs/en/getting-started

Enzyme

Enzyme is a JavaScript Testing utility for React that makes it easier to test your React Components’ output. You can also manipulate, traverse, and in some ways simulate runtime given the output. For more information checkout Enzyme official documentation.
