Ambient Context pattern for domain events with static call and mock replacement

DomainEvents.cs

public interface IDomainEventDispatcher
{
  void Dispatch<TEvent>(TEvent eventToDispatch) where TEvent : IDomainEvent;
}

public static class DomainEvents
{
  public static IDomainEventDispatcher Dispatcher { get; set; }
  
  public static void Raise<TEvent>(TEvent eventToRaise) where TEvent : IDomainEvent
  {
    Dispatcher.Dispatch(eventToRaise);
  }
}
    
    

// raise your events in domain entities
DomainEvents.Raise(new NameChangedEvent(person.PersonId, person.Name));

//Unit test your dispatcher
var domainEventsDispatcher = new Mock<IDomainEventDispatcher>();
DomainEvents.Dispatcher = domainEventsDispatcher.Object;
