assert.match(
  convertHTML('Hamburgers < Pizza < Tacos'),
  /Hamburgers &lt; Pizza &lt; Tacos/
);

convertHTML("Sixty > twelve") should return the string Sixty > twelve.

assert.match(convertHTML('Sixty > twelve'), /Sixty > twelve/);

convertHTML('Stuff in "quotation marks"') should return the string Stuff in "quotation marks".

assert.match(
  convertHTML('Stuff in "quotation marks"'),
  /Stuff in "quotation marks"/

            "'": '&apos;'};
