Jest 29 is here, just a few short months after Jest 28. As mentioned in the Jest 28 blog post, this version contains just a couple of breaking changes, in order to make the upgrade as smooth as possible.

Jest is a JavaScript testing framework developed by Facebook, designed to simplify the process of writing and running tests for JavaScript applications, particularly those built with React. With features such as snapshot testing, mocking, and code coverage reporting, Jest enables developers to write  and reliable tests for their JavaScript codebases. Developers can learn how to use Jest to write effective unit tests, integration tests, and end-to-end tests for their applications, ensuring code quality and stability throughout the development lifecycle.
