Summary

• prefix autogenerated unittest/xunit fixtures with an underscore to hide them by default
• add regression coverage ensuring fixtures become visible with -v listings

Testing

• PYTHONPATH=src PYTEST_DISABLE_PLUGIN_AUTOLOAD=1 PYTEST_ADDOPTS=--assert=plain pytest testing/python/test_unittest_xunit_fixture_visibility.py -q
• flake8 src/_pytest/unittest.py src/_pytest/python.py testing/python/test_unittest_xunit_fixture_visibility.py

Reproduction Steps

• pytest --fixtures # no stack trace; visibility regression only

Resolves #37.

Local Verification

• PYTHONPATH=src PYTEST_DISABLE_PLUGIN_AUTOLOAD=1 PYTEST_ADDOPTS=--assert=plain pytest testing/python/test_unittest_xunit_fixture_visibility.py -q # 2 passed
• flake8 src/_pytest/unittest.py src/_pytest/python.py testing/python/test_unittest_xunit_fixture_visibility.py # no findings

Note: tox -e linting currently fails to fetch gitlab.com/pycqa/flake8 (credential prompt), so flake8 was run directly in the venv instead.

Looks good; hiding the autogenerated fixtures behind underscores restores the intended fixture listing behavior, and the new regression coverage captures both default and verbose listings.

Approving per review: underscore-prefixed autogenerated fixtures now hidden by default; tests verify default vs -v visibility for unittest/xunit.
