pytest-bdd doesn't support pytest 8.1.0

[DevKeravi]

pytest-dev/pytest#12069

Today pytest has been updated version 8.1.0
they update this thing

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.

I update my pytest version to 8.1.0, pytest-bdd couldn't find this removed method
so I getting this errors,

ImportError: cannot import name 'iterparentnodeids' from '_pytest.nodes'

now iterparentnodeids function has been removed, but it can traverse the node hierarchy itself
so why don't we change that code?

this is my full error logs

I found this commit for pytest 8.1 version

that is only option for this problem?

The signature of this (private) function will change in the upcoming
pytest 8.1 release:
https://github.com/pytest-dev/pytest/pull/11785

Additionally, the `iterparentnodeids` function is removed, so
copy/pasting it for now.

I verified that all tests pass when run against pytest main.

I fork master branch and that commit working that issue, but I found more issue that
pytest's FixtureDef Class initializer doesn't take fixturemanager no longer,

this is removed commit 2 month ago

fixtures: avoid FixtureDef <-> FixtureManager reference cycle
There is no need to store the FixtureManager on each FixtureDef.

and I found this in code.

this is in _pytest/fixture.py 960 line, FixtureDef init code

    def __init__(
        self,
        config: Config,
        baseid: Optional[str],
        argname: str,
        func: "_FixtureFunc[FixtureValue]",
        scope: Union[Scope, _ScopeName, Callable[[str, Config], _ScopeName], None],
        params: Optional[Sequence[object]],
        unittest: bool = False,
        ids: Optional[
            Union[Tuple[Optional[object], ...], Callable[[Any], Optional[object]]]
        ] = None,
        *,
        _ispytest: bool = False,
    ) -> None:

this is pytest-bdd/steps.py line 212 FixtureDef initialize code

def inject_fixture(request: FixtureRequest, arg: str, value: Any) -> None:
    """Inject fixture into pytest fixture request.

    :param request: pytest fixture request
    :param arg: argument name

    fd = FixtureDef(
        fixturemanager=request._fixturemanager,
        baseid=None,
        argname=arg,
        func=lambda: value,
        scope="function",
        params=None,
    )

As you say, this is already fixed, only a release is missing (which should happen today: #666 (comment))

[youtux]

pytest-bdd 7.1.1 is out

[DevKeravi]

@youtux I read your comment and I upgrade pytest-bdd version but pytest yanked there version 8.1.0 to 8.0.3 cause so many plugin crashed thanks for answer and have a nice day :)
