  # We have a little utility method that you can manually uncomment to
  # generate what the current iteration of the QuotedHTMLParser things the
  # `removeQuotedHTML` should look like. These can be manually inspected in
  # a browser before getting their filename changed to
  # `email_#{n}_stripped.html". The actually tests will run the current
  # iteration of the `removeQuotedHTML` against these files to catch if
  # anything has changed in the parser.
  #
  # It's inside of the specs here instaed of its own script because the
  # `QuotedHTMLParser` needs Electron booted up in order to work because
  # of the DOMParser.
