Developed by Facebook, Jest is a delightful JavaScript Testing Framework with a focus on simplicity. It has become the most popular choice for testing JavaScript applications, particularly those built with React. Its speed and powerful features provide an excellent developer experience.
Jest is designed to work out of the box on most JavaScript projects and is optimized for performance, running tests in parallel to provide fast feedback.
It includes a test runner, a built-in assertion library, and powerful mocking capabilities, providing a complete solution for testing JavaScript code.
Jest's mocking features make it easy to isolate units of code and mock dependencies like functions, modules, and timers, enabling true unit testing.
