How can I use jest fake timers when testing code that use p-queue?

[bluprince13]

I am trying to test my code that makes use of p-queue.

However, I don't want my test to actually wait for seconds. I tried to use https://jestjs.io/docs/timer-mocks.

jest.useFakeTimers();

I also tried to mock setTimeout myself

       const setTimeoutCopy = setTimeout
       let waitingTime = 0
       jest.spyOn(global, "setTimeout").mockImplementation((f, ms) => {
            waitingTime += ms
            return setTimeoutCopy(f, 0)
        })

However, this seems to have no effect on p-queue.

And my test times out with:

Error: thrown: "Exceeded timeout of 5000 ms for a test.
Use jest.setTimeout(newTimeout) to increase the timeout value, if this is a long-running test."

Would appreciate some guidance.
