Overall I think the testing here is an OK start, but it would be good to test properties more thoughtfully. That's a bit hard given the simplistic node structures. 

I think it would be beneficial if these nodes could do things like insert new children, update text, etc.  Maybe that's the responsibility of another data structure to you, but its very typical to have at least an interface to add/remove children and provide ways to performa the basic operations. That would make this patch a lot more complete. Alternativly, I'd be fine if the plan was to do that in another change.
