Comment:
@bobertlo, your particular comment in all these commits caught my interest.

```sh
# pytest marked deprecated, suggests using tox (which does not test against system packages)
```

You see, I too got entrapped with tests (PR #34489) and it seems I have to explicitly specify `python3-pytest` in `checkdepends` along with packages it uses during tests.

If `python3-pytest` is not defined, `do_check` falls back to that "deprecated testing" which you mentioned.

```sh
do_check() {
    if python3 -c 'import pytest' >/dev/null 2>&1; then
        PYTHONPATH="$(cd build/lib* && pwd)" \
            python3 -m pytest ${make_check_args} ${make_check_target}
    else
        # Fall back to deprecated setup.py test orchestration without pytest
        if [ -z "$make_check_target" ]; then
            if ! python3 setup.py --help test >/dev/null 2>&1; then
                msg_warn "No command 'test' defined by setup.py.\n"
                return 0
            fi
        fi

        : ${make_check_target:=test}
        python3 setup.py ${make_check_target} ${make_check_args}
    fi
}
```

To be certain, the `python3-module` build style does not append `python3-pytest` to anywhere.

As you can see above, it is mentioned only within `do_check`.

Hope this information will be useful for you.
