# jestPlugin

`jestPlugin` exposes Rslint's built-in implementation of supported rules from [`eslint-plugin-jest` 29.x](https://github.com/jest-community/eslint-plugin-jest/tree/v29.16.0). Its presets follow the corresponding upstream flat configurations.

```ts
import { defineConfig, jestPlugin } from '@rslint/core';

export default defineConfig([
  {
    ...jestPlugin.configs.recommended,
    files: ['**/*.{test,spec}.{js,mjs,jsx,ts,tsx,mts}'],
  },
]);
```

`jestPlugin.configs.recommended` does not declare `files`; the example scopes it to test and spec files.
All Jest presets include the globals exposed by the Jest runtime.
