Symbolic link components are no longer resolved in conftest paths. This means that if a conftest appears twice in collection tree, using symlinks, it will be executed twice. For example, given
tests/real/conftest.py tests/real/test_it.py tests/link -> tests/real
running pytest tests
now imports the conftest twice, once as tests/real/conftest.py
and once as tests/link/conftest.py
.
This is a fix to match a similar change made to test collection itself in pytest 6.0 (see :pull:`6523` for details).
