[Bug]: Looks like injectGlobals: false affects fake timers

[krutoo]

Version

29.7.0

Steps to reproduce

1. clone https://github.com/krutoo/testing-library-user-event-with-fake-timers
2. `npm install
3. npm run test

Expected behavior

Tests done

Actual behavior

line

await user.click(getByTestId("counter"));

won't resolve and test fails by timeout with error:

thrown: "Exceeded timeout of 5000 ms for a test.
    Add a timeout value to this test to increase the timeout, if this is a long-running test. See https://jestjs.io/docs/api#testname-fn-timeout."

Additional context

I noticed that in @testing-library/user-event library there is some code like this:

Promise.all([
    new Promise((resolve) => {
        globalThis.setTimeout(() => resolve(), delay)
    }),
    config.advanceTimers(delay)
]);

config.advanceTimers is option - https://testing-library.com/docs/user-event/options/#advancetimers

This promise resolves as expected but in test there is no resolve or reject, it just freezes.

I think this is because fake timers affects microtasks mechanism or something else.

FWIW, I think this is a testing-library issue, not a jest one. I have opened an issue with the relative explanation and possible fixes in: testing-library/dom-testing-library#1286 .

[SimenB]

Yeah, nothing in jest itself breaks on missing globals, so downstream assumptions are almost certainly where things go awry
