How to fix warning `An update to TimerRoot inside a test was not wrapped in act(...)` with timers?

[blasdfaa]

tests are running correctly, but a warning appears in console. How can I fix this?

Warning: An update to TimerRoot inside a test was not wrapped in act(...).

When testing, code that causes React state updates should be wrapped into act(...):

act(() => {
  /* fire events that update state */
});
/* assert on the output */

vi.advanceTimersByTime is sync timer. if u want async timer, use vi.advanceTimersByTimeAsync

await act(async () => vi.advanceTimersByTimeAsync(1000));
