Could you add some specifics to this? Do you want the unit tests listed in the "Referenced By" tab for the model?

What does "with an accompanying page showing the fixtures being used" mean? How would you get to the "accompanying page"? What does it look like?

From there I can click into a page for the data test:

Would be nice to have some similar page you could click into for the unit test with the description, depends on, and such.
