Jest

Delightful JavaScript testing framework

About Jest

Jest is a JavaScript testing framework built for JavaScript developers who need to test code with a focus on simplicity and zero config. It provides snapshot testing mocking and parallel workers, so teams can cover large codebases with readable tests assembling multiple testing libraries manually. The workflow keeps setup practical for everyday use, with documentation and integrations that fit existing stacks rather than forcing a complete replacement of tools a team already relies on daily.
