Package Exports

eslint-plugin-jest

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (eslint-plugin-jest) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

eslint-plugin-jest

Eslint plugin for Jest

Installation

$ yarn add --dev eslint eslint-plugin-jest

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

Usage

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

{
  "plugins": [
    "jest"
  ]
}

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

{
  "rules": {
    "jest/no-disabled-tests": "warn",
    "jest/no-focused-tests": "error",
    "jest/no-identical-title": "error",
    "jest/valid-expect": "error",
  }
}

You can also whitelist the environment variables provided by Jest by doing:

{
  "env": {
    "jest/globals": true
  }
}

Supported Rules

no-disabled-tests - disallow disabled tests.
no-focused-tests - disallow focused tests.
no-identical-title - disallow identical titles.
valid-expect - ensure expect is called correctly.
