{"library":"jest-cli","type":"library","category":null,"description":"Jest is a popular and delightful JavaScript testing framework known for its focus on simplicity, performance, and features like snapshot testing and built-in mocking. It offers a powerful command-line interface (CLI) to run tests, generate coverage reports, and interact with the test runner. The current stable version is 30.3.0, released after a significant three-year development cycle for version 30.0.0, with a stated aim for more frequent major releases going forward. Jest differentiates itself with an 'all-in-one' approach, providing an assertion library, test runner, and mocking capabilities out of the box, often requiring minimal configuration for many projects. It supports TypeScript out-of-the-box and is widely adopted across various JavaScript environments, including Node.js, React, Angular, and Vue projects.","language":"javascript","status":"active","version":"30.3.0","tags":["javascript","ava","babel","coverage","easy","expect","facebook","immersive","instant","typescript"],"last_verified":"Wed May 27","install":[{"cmd":"npm install jest-cli","imports":["import { defineConfig } from 'jest-config';","import { jest } from '@jest/globals';","import { expect } from '@jest/globals';"]},{"cmd":"yarn add jest-cli","imports":[]},{"cmd":"pnpm add jest-cli","imports":[]}],"homepage":"https://jestjs.io","github":"https://github.com/jestjs/jest","docs":null,"changelog":null,"pypi":null,"npm":"https://www.npmjs.com/package/jest-cli","openapi_spec":null,"status_page":null,"smithery":null,"compatibility":{"summary":{"python_range":"18–22","success_rate":0,"avg_install_s":null,"avg_import_s":null,"wheel_type":null},"url":"https://checklist.day/v1/registry/jest-cli/compatibility"}}
