[3.17] PytestUnknownMarkWarning: Unknown pytest.mark.regression

[picca]

Hello,

during the Debian packaging, I have this warning message.

Is it normal ?

this does not fail but I am wondering if something is not register correctly in pytest.

sorry if this is just noise.

I use this script in order to run the test

set -efu
pythons=$(py3versions -r 2>/dev/null)
cp -r dxtbx/tests dxtbx/conftest.py "$AUTOPKGTEST_TMP"
cd "$AUTOPKGTEST_TMP"
for py in $pythons; do
    echo "Testing dxtbx with $py:"
    $py -m pytest \
        --ignore tests/command_line/test_dlsnxs2cbf.py \
        --ignore tests/format/test_FormatNXmx.py \
