If you look at the log,
https://ci.debian.net/packages/d/diffoscope/testing/amd64/

you can see that pytest-with-recommends works, because it installs ocaml-nox,
while pytest doesn't...

look at debian/tests/control

Tests: pytest
Depends: diffoscope, python3-pytest, file, python3-tlsh

I would expect either:
1) ocaml-nox to become a runtime dependency for pytest test
2) test being skipped when ocaml-nox is not installed
3) ocaml-nox become a runtime dependency of diffoscope.

I don't really know which one is better, I think 2),
but since it requires code modifications, I went for 1) in Ubuntu
https://launchpad.net/ubuntu/+source/diffoscope/123ubuntu1

(lets see how it goes)
