let text = 'Lorem ipsum dolor sit amet, //sindresorhus.com consectetuer adipiscing http://yeoman.io elit.'
let urlsSet = getUrls( text,
  {
    'stripAuthentication': true,
    'stripHash': true,
    'sortQueryParameters': true,
    'stripWWW': false,
    'extractFromQueryString': true
  } );

The following exception will get thrown:
