I am using Cypress as Component Test for Angular.
The component uses a service that changes a BehaviourSubject.
After each test i need to reset the BehaviourSubject -> how can i access it?

The Service is injected in the Constructor (but as private). In the cy-spec file i have it as provider but not as mock.
Is there a way to call a clear method on the service?
Or do i have to use a mock?

In general cypress can not access private members/methods/providers?!
