Jest Codemods

jest-codemods is a utility package providing a collection of automated code transformations (codemods) designed to simplify the migration of existing JavaScript and TypeScript test files to the Jest testing framework. It supports migrations from a wide array of popular testing libraries, including AVA, Chai, Expect.js, Jasmine, Mocha, proxyquire, Should.js, Tape, Sinon, and Node-Tap. Currently at version 0.35.0, the project maintains an active release cadence, frequently incorporating new features, bug fixes, and dependency updates. Its primary differentiator is the comprehensive support for various source frameworks, offering both an interactive command-line interface (CLI) for ease of use and direct integration with jscodeshift for more granular control over transformations, making it an indispensable tool for projects transitioning to Jest by significantly reducing manual refactoring efforts.
