Test a depencendy function inside same file in jest

If I have a js file like:

  const doSomething = async (obj, time) => {
    // ...
  };

  const throttledDoSomething = (obj, time) => {
    const throttleTime = time + SOME_DELTA_VALUE;
    return throttle(() => doSomething(elem, time), throttleTime);
  };

How can i mock the call for doSomething when testing throttledDoSomething in jest?

I saw this question that answers it for jasmine, but I would like to stick to using jest. Also if anyone has tips on best practices in situations like that, it would be appreciated.
