Expectations for nodeid of items located outside the rootdir

[spadman1]

Is it expected behavior for the nodeid of items collected from python files located outside the rootdir to look like ::some_test_name, instead of some_module.py::some_test_name. The sample test below illustrates a situation where nodeid of all the test items is of the form ::some_test_name.

import tempfile
import textwrap
from pathlib import Path

import pytest

@pytest.fixture()
def test_file_outside_rootdir():
    with tempfile.TemporaryDirectory() as tmp_path:
        root_dir = Path(tmp_path)
        testdir = root_dir.joinpath("sub-directory")
        testdir.mkdir(parents=True, exist_ok=False)
        filename = testdir.joinpath("test_foo.py")
        data = textwrap.dedent(
            """
            import pytest

            @pytest.mark.parametrize("x", [1, 2, 3])
            def test_parametrized_function_outside_rootdir(request: pytest.FixtureRequest, x: int):
                assert not request.node.nodeid.startswith("::")

            def test_function_outside_rootdir(request: pytest.FixtureRequest):
                assert not request.node.nodeid.startswith("::")

            class TestFoo:
                def test_class_method_outside_rootdir(self, request: pytest.FixtureRequest):
                    assert not request.node.nodeid.startswith("::")
            """
        )
        filename.write_text(data, encoding="utf-8")
        yield filename

def test_pycollect_test_function_outside_rootdir(pytester: pytest.Pytester, test_file_outside_rootdir: Path):
    pytester.makefile(".ini", pytest=f"[pytest]\naddopts =\n")

    result = pytester.runpytest(str(test_file_outside_rootdir), "--rootdir", pytester.path, "-vv", "-s")
    result.assert_outcomes(failed=0, passed=5)
    assert result.ret == pytest.ExitCode.OK

The currently observed behavior seems to be the outcome of the function _check_initialpaths_for_relpath (in _pytest/nodes.py)

Thanks for pointing out the issue related to my question.
