How to create mock NgZone in angular testing

I have a component that takes NgZone as a provider. How can I make a provider for NgZone when creating the TestBed.

I tried this but the test is timing out

const mockNgZone = jasmine.createSpyObj('mockNgZone', ['run', 'runOutsideAngular'])
mockNgZone.run.and.callFake(fn => fn())

When I use this mockNgZone, the test is timing out with the error:

Disconnected (1 times), because no message in 10000 ms.
Electron 1.7.9 (Node 7.9.0) ERROR
   Disconnected, because no message in 10000 ms.

The run and runOutsideAngular methods of NgZone return value from the executed function. So, please return some value from the callFake function.

Example:-

mockNgZone.run.and.callFake(function () {return something;});
