Testing mouse event listener added using ref in React functional component

Hi I have a functional component as shown below:

import React, { useRef, useEffect, useState } from 'react';

const SomeComponent = ({ prop1, ...otherProps}) => {
  const divRef = useRef();

  useEffect(() => {
    divRef.current.addEventListener('mousedown', mouseDownFunc);
  }, []);

  const mouseDownFunc = () => {
    document.addEventListener('mousemove', (el) => {
        // call some parent function
    });
  }

  return (
    <div
        className='test-div'
        ref={ divRef }>
    </div>
  );
};

How do I test a react functional component wherein addEventListener is added using ref inside useEffect which when triggered calls mouseDownFunc. I'm new to react jest testing, little confused on how to do it.
