Pytest 8.2.0: AttributeError: 'FixtureDef' object has no attribute 'unittest' when using

[yanksyoon]

When using with the most recent version of pytest 8.2.0, asyncio-0.21.1 is used which breaks the fixtures with error: AttributeError: 'FixtureDef' object has no attribute 'unittest'.

To reproduce:

1. Minimal tox.ini in project root.

[tox]
skipsdist=True
skip_missing_interpreters = True
envlist = unit

[vars]
src_path = {toxinidir}/src/
tst_path = {toxinidir}/tests/
;lib_path = {toxinidir}/lib/charms/operator_name_with_underscores
all_path = {[vars]src_path} {[vars]tst_path}

[testenv]
basepython = python3.10
setenv =
  PYTHONPATH = {toxinidir}:{toxinidir}/lib:{[vars]src_path}
  PYTHONBREAKPOINT=ipdb.set_trace
  PY_COLORS=1
passenv =
  PYTHONPATH

[testenv:integration]
description = Run integration tests
pass_env =
    PYTEST_ADDOPTS
deps =
    pytest
    pytest-asyncio
    pytest-operator
commands =
    pytest -v --tb native --log-cli-level=INFO

2. Create test file tests/integratin/test_asyncio.py

import logging

import pytest
import pytest_asyncio

logger = logging.getLogger(__name__)


@pytest_asyncio.fixture(name="buggy")
async def async_fixture():
    logger.info("SETUP FIXTURE")
    return "buggy"


@pytest.mark.asyncio
async def test_buggy(buggy):
    logger.info("TESTING")
    print(f"hello {buggy}")

The test will fail.

Btw for anyone that is experiencing the issue - downgrade pytest pytest==8.1.1 to mitigate issue for now.

Resolved now by new pytest-asyncio==0.21.2
