`iterparentnodeids` removed from pytest #668

Closed The-Compiler closed 7 months ago

Running against the current pytest main branch results in:

ImportError: cannot import name 'iterparentnodeids' from '_pytest.nodes' (/__w/qutebrowser/qutebrowser/.tox/bleeding-qt5/lib/python3.11/site-packages/_pytest/nodes.py)

due to:

Relevant changelog entry:

  • The _pytest.nodes.iterparentnodeids() function is removed without replacement. Prefer to traverse the node hierarchy itself instead. If you really need to, copy the function from the previous pytest release.

Relevant code from before it was removed (with SEP = "/"):

def iterparentnodeids(nodeid: str) -> Iterator[str]:
    """Return the parent node IDs of a given node ID, inclusive.
    For the node ID
        "testing/code/test_excinfo.py::TestFormattedExcinfo::test_repr_source"
    the result would be
        ""
        "testing"
        "testing/code"
        "testing/code/test_excinfo.py"
        "testing/code/test_excinfo.py::TestFormattedExcinfo"
        "testing/code/test_excinfo.py::TestFormattedExcinfo::test_repr_source"
    Note that / components are only considered until the first ::.
    """
    pos = 0
    first_colons: Optional[int] = nodeid.find("::")
    if first_colons == -1:
        first_colons = None
    # The root Session node - always present.
    yield ""
    # Eagerly consume SEP parts until first colons.
    while True:
        at = nodeid.find(SEP, pos, first_colons)
        if at == -1:
            break
        if at > 0:
            yield nodeid[:at]
        pos = at + len(SEP)
    # Eagerly consume :: parts.
    while True:
        at = nodeid.find("::", pos)
        if at == -1:
            break
        if at > 0:
            yield nodeid[:at]
        pos = at + len("::")
    # The node ID itself.
    if nodeid:
        yield nodeid

Thanks for reporting this, fixed in https://github.com/pytest-dev/pytest-bdd/pull/666
