CommonDomain - how to unit test aggregate root

I have a small system that uses Jonathan Oliver's CommonDomain and EventStore. How can I unit test my aggregate roots in order to verify that correct events are raised? Consider following aggregate root: ``` public class Subscriber : AggregateBase { private Subscriber(Guid id) { this.Id = id; } private Subscriber(Guid id, string email, DateTimeOffset registeredDate) : this(id) { this.RaiseEvent(new NewSubscriberRegistered(this.Id, email, registeredDate)); } public string Email{ get; private set; } public DateTimeOffset RegisteredDate { get; private set; } public static Subscriber Create(Guid id, string email, DateTimeOffset registeredDate) { return new Subscriber(id, email, registeredDate); } private void Apply(NewSubscriberRegistered @event) { this.Email = @event.Email; this.RegisteredDate = @event.RegisteredDate; } } ``` I would like to write a following test: ``` // Arrange var id = Guid.NewGuid(); var email = "test@thelightfull.com"; var registeredDate = DateTimeOffset.Now; // Act var subscriber = Subscriber.Create(id, email, registeredDate); // Assert var eventsRaised = subscriber.GetEvents(); <---- How to get the events? // Assert that NewSubscriberRegistered event was raised with valid data ``` I could set up whole EventStore with memory persistence and synchronous dispatcher, hook up mock event handler and store any published events for verification, but it seems a bit of overkill. There is an interface `IRouteEvents` in CommonDomain. Looks like I could mock it to get the events directly from `AggregateBase` but how would I actually pass it to my `Subscriber` class? I don't want to 'pollute' my domian with testing-related code.
