Request a url and scrape the metadata from its HTML using Node.js or the browser.

  try {
    const metadata = await urlMetadata(url, {
      maxRedirects: 0
    })
    // the ^code above should throw an error
    // if the following line fails it means
    // the test did not throw the proper error:
    expect(metadata.url).toBe(undefined)
  } catch (err) {
