Jest
Delightful JavaScript Testing Framework with a focus on simplicity
Jest is an open-source JavaScript testing framework designed for simplicity and ease of use. It works out of the box with zero configuration on most JavaScript projects and supports features like snapshot testing, code coverage, parallelized test runs, and rich mock functions. It is widely used for unit and integration testing across JavaScript and TypeScript codebases.
Jest provides a zero-config, all-in-one testing framework that runs tests in isolated parallel processes with built-in support for snapshots, mocking, and code coverage.
