Are there not already archetypes like these in `test/support`? 
I would really rather not duplicate them if-so.

Additionally, I don't love the relative include of such a header with such a non-descript name.
If these types aren't reusable, could you explain why? And if they are, could we put them in `test/support` and give the header a better name.
