Readme
ESLint plugin to follow best practices and anticipate common mistakes when writing tests with jest-dom.
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
.
[!NOTE]
eslint.config.js
is supported, though most of the plugin documentation still currently uses.eslintrc
syntax; compatible versions of configs are available prefixed withflat/
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",
},
};
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"],
},
];
💼 Configurations enabled in.
✅ Set in the recommended
configuration.
🔧 Automatically fixable by the --fix
CLI option.
💡 Manually fixable by editor suggestions.
