   it works with

   jest.useFakeTimers({ advanceTimers: true });
   // OR 
   jest.useFakeTimers({ doNotFake: ["nextTick"] }); // if you really don't want process.nextTick to be monkey patched
   

   because dataloader uses process.nextTick (if in node)

   however, I still haven't figured out how to advance the timers properly to test the dataloader itself
