Installation

This module is distributed via npm which is bundled with node and should be installed as one of your project's devDependencies:

npm install --save-dev eslint-plugin-jest-dom

This library has a required peerDependencies listing for ESLint.

Usage

> [!NOTE] > > eslint.config.js is supported, though most of the plugin documentation still > currently uses .eslintrc syntax; compatible versions of configs are available > prefixed with flat/ and may be subject to small breaking changes while ESLint > v9 is being finalized. > > Refer to the > ESLint documentation on the new configuration file format > for more.

Add jest-dom to the plugins section of your .eslintrc.js configuration file. You can omit the eslint-plugin- prefix:

module.exports = {
  plugins: ["jest-dom"],
  rules: {
    // your configuration
  },
};

Then configure the rules you want to use under the rules section.

module.exports = {
  rules: {
    "jest-dom/prefer-checked": "error",
    "jest-dom/prefer-enabled-disabled": "error",
    "jest-dom/prefer-required": "error",
    "jest-dom/prefer-to-have-attribute": "error",
  },
};

Recommended Configuration

This plugin exports a recommended configuration that enforces good jest-dom practices (you can find more info about enabled rules in Supported Rules section).

To enable this configuration with .eslintrc, use the extends property:

module.exports = {
  extends: "plugin:jest-dom/recommended",
  rules: {
    // your configuration
  },
};

To enable this configuration with eslint.config.js, use jestDom.configs['flat/recommended']:

module.exports = [
  {
    files: [
      /* glob matching your test files */
    ],
    ...require("eslint-plugin-jest-dom").configs["flat/recommended"],
  },
];
