+Furthermore, a ``ResourceWarning`` is a special case in Python, because it is usually not triggered directly
+by the code causing the leak (like an unclosed file), but by the Python interpreter during
+garbage collection.
+
+Because of this, trying to use ``@pytest.mark.filterwarnings("error::ResourceWarning")`` or
+similar filters to turn them into errors will not work as expected because the warning is raised later and
+caught by pytest internally, emitting a :class:`pytest.PytestUnraisableExceptionWarning`.
+
+To properly catch and filter these, you must also add a filter for the unraisable exception:

+
+    import pytest
