Well -- ert-deftest doesn't record what file it's from, I think?
Looking at the definition, it just adds the test to the symbol-plist.
So that macro would also have to stash the file name somewhere.
load-history would be possible (but sounds unclean), so stashing it in
the symbol-plist would be better.

Then find-definition-noselect could be extended to use that for this
type.
