Close #38851, support `jest` fakeTimers APIs' integration with `fakeAsync()`. After enable this feature, calling `jest.useFakeTimers()` will make all test run into `fakeAsync()` automatically. ``` beforeEach(() => { jest.useFakeTimers('modern'); }); afterEach(() => { jest.useRealTimers(); }); test('should run into fakeAsync() automatically', () => { const fakeAsyncZoneSpec = Zone.current.get('FakeAsyncTestZoneSpec'); expect(fakeAsyncZoneSpec).toBeTruthy(); }); ``` Also there are mappings between `jest` and `zone` APIs. - `jest.runAllTicks()` will call `flushMicrotasks()`. - `jest.runAllTimers()` will call `flush()`. - `jest.advanceTimersByTime()` will call `tick()` - `jest.runOnlyPendingTimers()` will call `flushOnlyPendingTimers()` - `jest.advanceTimersToNextTimer()` will call `tickToNext()` - `jest.clearAllTimers()` will call `removeAllTimers()` - `jest.getTimerCount()` will call `getTimerCount()` PR Close #39016
