Speaking as a tool author, these are two rather different categories
which should not be merged. I personally would put "tools with defined
tests but missing input/output files" under "failing tests" not under
"missing tests".

No it isn't easily viewable - it is easy to get a combined listing of
repositories with (a) missing tests and/or (b) tests with missing files,
and then very tedious to look at these repositories one by one to see
which it is.

I wasn't meaning to suggest you do that though - you're already
able to short cut these cases and mark the test as failed. These
are the quickest possible tests to run - they fail at the first hurdle.

Yes, and that is fine - I'm merely talking about how this information
is presented to the Tool Shed viewer.

Indeed, but it this is a failing test and should (in my view) be
listed under failing tests not under missing tests.

We're just debating where to list such problem tools/repositories
in the Tool Shed's test results interface.
