I don't see it being invoked anywhere,

It is invoked in `t/t0032-reftable-unittest.sh`:

Ah, thank you. I was looking at what Junio has queued in hn/reftable.

but presumably if we were to add support to our test suite, we'd have a
script which invokes it within a scratch directory.

I agree that it would make most sense for t0032 to prefix the call to
`test-tool` with `TMPDIR=$PWD`.

Yep, that would be fine.

I'm not sure if the long-term goal is to have this opaque unit-test
program or not. If it is, I was likewise going to suggest that its
ad-hoc output be replaced with TAP. But it looks like on your branch
that "test-tool reftable" does not produce output at all. So I may be a
bit behind on what the current state and forward plans are...
