ESLint

Installation

npm:

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

Yarn:

yarn add --dev eslint eslint-plugin-jest-extended

Note: If you installed ESLint globally then you must also install eslint-plugin-jest-extended globally.

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

{
  "plugins": ["jest-extended"]
}

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

{
  "rules": {
    "jest-extended/prefer-to-be-true": "warn",
    "jest-extended/prefer-to-be-false": "error"
  }
}
