Answer 1

I was still getting some errors because I was using moment-timezone, too. So, here's what I did to fix that:

let diffMins = updateThreshold + 1;
jest.mock('moment', () => {
  const mMoment = {
    diff: jest.fn(() => diffMins),
  };
  const fn = jest.fn(() => mMoment);
  fn.version = '2.24';
  fn.tz = jest.fn();
  fn.fn = jest.fn();
  return fn;
});
