如何在笑话中暂停承诺?

const delay = (time, value) => {
  return Promise.resolve(); //  THIS WORKS

  // NEED TO, but wont work
  return new Promise(function(resolve) {
    setTimeout(() => resolve(value), time);
  });
};


const request = (count) => {
  if (count === 15) return;
  return makeRequest().then(
    res => Promise.resolve() // if it works it works.
  ).catch(
    err => delay(1000).then(() => request(count - 1));
  )
}

describe("on fail", () => {
  beforeEach(() => jest.useFakeTimers());
  it("should retry 15 times", async () => {

    request();
    jest.runTimersToTime(15001); // alias `advanceTimersByTime`
    await expect(request.mock.calls.length).toBe(15); // what am i missing? or rather, what's jest missing?
  });
});
