PLEASE CHECK THIS REPO WITH THE EXAMPLES THAT YOU CAN RUN:
https://github.com/apieceofbart/async-testing-with-jest-fake-timers-and-promises

// Let's say you have a function that does some async operation inside setTimeout (think of polling for data)

function runInterval(callback, interval = 1000) {
  setInterval(async () => {
    const results = await Promise.resolve(42) // this might fetch some data from server
    callback(results)
  }, interval)
