PostCSS Tape

PostCSS Tape lets you quickly test PostCSS plugins.

1. Install this dependency to your project:

   npm install postcss-tape --save-dev

2. Add the postcss-tape task to your package.json:

   {
      "scripts": {
        "test": "postcss-tape"
      }
   }

3. Add tests to your .tape.js file:

   module.exports = {
     'postcss-my-plugin': {
       'basic': {
         message: 'supports basic usage'
       }
     }
   };

That’s it! Empty tests will be auto-generated. Now you can use the tape task:

npm run tape

Options may be passed through package.json using postcssConfig:

{
  "postcssConfig": {
    "plugin": "path/to/plugin.js",
    "config": "path/to/.tape.js",
    "fixtures": "path/to/cssdir"
  }
}

Options may be passed through arguments:

postcss-tape --plugin=path/to/plugin.js --config=path/to/.tape.js
