Installation

You'll first need to install ESLint:

$ yarn add eslint --dev

Next, install eslint-plugin-jest-formatting:

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

Note: If you installed ESLint globally (using the -g flag) then you must also install eslint-plugin-jest-formatting globally.

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

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

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

{
  "rules": {
    "jest-formatting/padding-around-describe-blocks": 2,
    "jest-formatting/padding-around-test-blocks": 2
  }
}

or

You can use our "recommended" settings which enables most of the rules for you

{
  "extends": ["plugin:jest-formatting/recommended"]
}

We also support a "strict" settings which enabled all of the rules for you

{
  "extends": ["plugin:jest-formatting/strict"]
}

This provides an extensive set of jest eslint rules
