How to use the @cumulus/common/test-utils.randomId function in @cumulus/common

function fakeUserFactory(params = {}) {
  const user = {
    userName: randomId('userName'),
    password: randomId('password'),
    expires: Date.now() + (60 * 60 * 1000) // Default to 1 hour
  };

  return { ...user, ...params };
}

async function ensureAuthorizedOrRedirect(req, res, next) {
  // Skip authentication for debugging purposes.
  if (process.env.FAKE_AUTH) {
    req.authorizedMetadata = { userName: randomId('username') };
    return next();
  }

  // Public data doesn't need authentication
  if (isPublicRequest(req.path)) {
    req.authorizedMetadata = { userName: 'unauthenticated user' };
    return next();
  }

  const {
    accessTokenModel,
    authClient
  } = getConfigurations();

  const redirectURLForAuthorizationCode = authClient.getAuthorizationUrl(req.path);
  const accessToken = req.cookies.accessToken;
