plugins

Spec file plugin-spec.js shows how to load plugins while doing testing. The plugins might require options, which you can pass using array syntax

const use = [
  MyPlugin, // this plugin does not need options
  [MyPluginWithOptions, { label: 'testing' }], // this plugin needs options
]

// extend Vue with plugins
const extensions = {
  use,
}

mount({}, { extensions })
