How to run code before each test run in MSpec?

I am trying to run some initialization code before the test. I tried suggestions on other issues , but it doesn't seem to work. My domain model fires events through the following class:

public static class DomainEvents
{
    private static readonly object @lock = new object();
    private static Action<IDomainEvent> raiseEvent;

    public static void Raise<TEvent>(TEvent @event) where TEvent : class, IDomainEvent 
    {
         // omitted for brevity
    }

    public static void RegisterEventPublisher(Action<IDomainEvent> eventPublisher)
    {
        lock (@lock)
        {
            raiseEvent = eventPublisher;
        }
    }
}

For testing purposes, I would like to capture these events in a static list. What is the best way to do this?

  public class When_a_domain_event_is_raised

    It should_capture_the_event =
      () => DomainEventsContext.Events.ShouldContain(x => x.GetType() == typeof(FooEvent));
  }
}

RegisterEventPublisher RegisterEventSubscriber?
