AG creation events testing

[o-range]

In AggregateRootTestFixture events come to PublishedEvents list in
EventApplied handler

{
AggregateRoot =
CreationStrategy.CreateAggregateRoot<TAggregateRoot>();
...
AggregateRoot.InitializeFromHistory(stream);
...
AggregateRoot.EventApplied += (s, e) =>
PublishedEvents.Add(e.Event);
When();
}

but how can I get AG creationEvents list if the event appear in
constructor when no EventApplied handlers registred?
