@jest/types

This package contains shared types of Jest's packages.

If you are looking for types of Jest globals, you can import them from @jest/globals package:

import {describe, expect, it} from '@jest/globals'; describe('my tests', () => { it('works', () => { expect(1).toBe(1); }); });

If you prefer to omit imports, a similar result can be achieved installing the @types/jest package. Note that this is a third party library maintained at DefinitelyTyped and may not cover the latest Jest features.

Another use-case for @types/jest is a typed Jest config as those types are not provided by Jest out of the box:

// jest.config.ts import {Config} from '@jest/types'; const config: Config.InitialOptions = { // some typed config }; export default config;
