What is Jest?
Next.js allows you to use Jest for unit testing and snapshot testing. Jest is a JavaScript testing framework created by Facebook, designed for ensuring the correctness of JavaScript code, especially React applications. It provides a complete and easy-to-use solution for writing unit, integration, and end-to-end tests. Jest includes features like a test runner, assertion library, mocking capabilities, and code coverage reporting, making it a popular choice for developers looking to thoroughly test their code.
