stylelint-tape lets you test stylelint plugins.

Usage

Add stylelint-tape to your project:

npm install stylelint-tape --save-dev

Add a .tape.js file with tests:

module.exports = {
  'your/rule': [
    // test the # of warnings
    {
      source: 'body { top: 0 }',
      warnings: 1
    },
    // test for specific warnings
    {
      source: 'body { top: 0; left: 0 }',
      warnings: [
        'Unexpected "top" property.',
        'Unexpected "left" property.'
      ]
    },
    // test with arguments
    {
      source: 'body { top: 0 }',
      args: "always",
      warnings: 1
    },
    {
      source: 'body { top: 0 }',
      args: [ "always", { except: "top" } ]
    },
    // test autofixes
    {
      source: 'body { top: 0 }',
      expect: 'body { inset-block-start: 0 }'
    }
  ]
}

Use stylelint-tape in package.json to test your plugin:

{
  "scripts": {
    "test:plugin": "stylelint-tape"
  }
}

npm run test:plugin

Or, use it within Node.

const stylelintTape = require('stylelint-tape');
const plugin = require('path/to/plugin');

stylelintTape({ plugin: 'path/to/plugin.js' }, {
  'your/rule': [
    {
      source: 'body { top: 0 }',
      warnings: 1
    }
  ]
}).then(
  () => console.log('tests passed'),
  error => console.error('tests failed', error)
);
