  #### Type definitions
  -You may also want to install the [`@types/jest`](https://www.npmjs.com/package/@types/jest) module for the version of Jest you're using. This will help provide full typing when writing your tests with TypeScript.
  +There are two ways have [Jest global APIs](GlobalAPI.md) typed for test files written in TypeScript.
  -> For `@types/*` modules it's recommended to try to match the version of the associated module. For example, if you are using `26.4.0` of `jest` then using `26.4.x` of `@types/jest` is ideal. In general, try to match the major (`26`) and minor (`4`) version as closely as possible.
  +You can use type definitions which ships with Jest and will update each time you update Jest. Simply import the APIs from `@jest/globals` package:
  +
  +```ts title="sum.test.ts"
  +import {describe, expect, test} from '@jest/globals';
  +import {sum} from './sum';
  +
  +describe('sum module', () => {
  + test('adds 1 + 2 to equal 3', () => {
  + expect(sum(1, 2)).toBe(3);
  + });
  +});
  +```
  +
  +:::tip
  +
  +See the additional usage documentation of [`describe.each`/`test.each`](GlobalAPI.md#typescript-usage) and [`mock functions`](MockFunctionAPI.md#typescript-usage).
  +
  +:::
  +
  +Or you may choose to install the [`@types/jest`](https://npmjs.com/package/@types/jest) package. It provides types for Jest globals without a need to import them.
  ```bash npm2yarn
  npm install --save-dev @types/jest
  ```
  +
  +Note that `@types/jest` is a third party library maintained at [DefinitelyTyped](https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/jest), hence the latest Jest features or versions may not be covered yet. Try to match versions of Jest and `@types/jest` as closely as possible. For example, if you are using Jest `27.4.0` then installing `27.4.x` of `@types/jest` is ideal.
