@Pennycook can you review this? I think you're closer to this API than me, so you'd do a better job reviewing the test plan.

I didn't include any of the C++ 23 member functions in this test plan since I don't have a working implementation of <mdspan>. Adding these tests shouldn't be much work but it's difficult to do without this header since I can't be sure the tests actually compile and run correctly.

Could you use https://github.com/kokkos/mdspan? That's what I've used for mdspan experiments in the past.

I'll try using this to add the missing test cases.

Thanks!

What's here so far looks good to me. I've held off on approving to give @0x12CC a chance to experiment with kokkos/mdspan, as it would be nice to have the C++23 tests in place.

@Pennycook, I've updated this test plan to include tests for the five member functions that require C++ 23. I've also implemented the new tests in #1024 and tested them using the Kokkos reference <mdspan>.
