Configure stylelint

Add it to your Jest config

Using Built-in Preset

This package includes a Jest preset which configures Jest to run stylelint on all files supported by styleint. To use it set the following in your package.json:

{
  "jest": {
    "preset": "jest-runner-stylelint"
  }
}

or jest.config.js:

module.exports = {
  preset: "jest-runner-stylelint"
};
