Now you need to write:
results.OpenAndTurnoverEvents.Should().ContainInOrder(new[] { firstEvent.Code, secondEvent.Code, thirdEvent.Code });
With a params argument this would read better:
results.OpenAndTurnoverEvents.Should().ContainInOrder(firstEvent.Code, secondEvent.Code, thirdEvent.Code);
The only thing is that you cannot add a reason and readonArgs, but when you don't need that
results.OpenAndTurnoverEvents.Should().ContainInOrder(new[] { firstEvent.Code, secondEvent.Code, thirdEvent.Code });
