Inject the httpClient and another service into service with spectatot

[tamyfabius]

How to do with spectator in order to inject the httpClient and a service into another service
ex: new myService (httpClient, configService);

I know that to mock a Service that is injected into another service we can do this:

let spectator: SpectatorService<AuthService>;
const createService = createServiceFactory({
    service: AuthService,
    mocks: [DateService]
  });

And to test the httpClient we can do this:

let spectator: SpectatorHttp<TodosDataService>;
const createHttp = createHttpFactory(TodosDataService);

So my question is how do I inject the httpClient and another service (ConfigService in my case) into a service that I would like to test.
