queueMicrotask is not mocked by default, so I think you would need to add it to vi.useFakeTimers({ toFake: ['queueMicrotask'] }) https://vitest.dev/api/vi.html#vi-usefaketimers
from vitest.

Does this work?
import { vi, expect, test } from 'vitest'
test('Allow to encode and decode data', async () => {
vi.useFakeTimers();
const mock = vi.fn();
queueMicrotask(() => {
mock(1);
});
await vi.runAllTimersAsync()
expect(mock).toHaveBeenCalledWith(1);
});from vitest.

Minimal reproduction works when toFake is defined as instructed above.
https://stackblitz.com/edit/vitest-dev-vitest-nvum37?file=test%2Fbasic.test.ts.
import { vi, expect, test } from 'vitest';
test('Allow to encode and decode data', () => {
- vi.useFakeTimers();
+ vi.useFakeTimers({ toFake: ['queueMicrotask'] });
const mock = vi.fn();
queueMicrotask(() => {
mock(1);
});
vi.advanceTimersToNextTimer();
vi.advanceTimersByTime(2000);
expect(mock).toHaveBeenCalledWith(1);
});from vitest.
