Majority of the test failures was caused by python/cpython#144506, as proven by the monkey-patch in the last commit. There are still quite some suspicious test failures, will look into them as well.

justanotherariel · 2026-03-05T12:59:52Z

Looking at the test logs in the CI pipeline, there are 49 integrations failing tests: backblaze_b2, bang_olufsen, cloud, comelit, config_entries, demo, devolo_home_network, dsmr, emulated_kasa, energyid, ghost, go2rtc, growatt_server, hdmi_cec, helpers, hydrawise, image_processing, izone, kitchen_sink, knx, local_file, mcp_server, media_player, numato, openai_conversation, otbr, ping, plex, pterodactyl, rflink, ring, satel_integra, shelly, sonos, stream, switch, switch_as_x, synology_dsm, template, tplink, trane, tuya, twinkly, unifi, update, valve, wake_on_lan, waterfurnace, wemo.

Also running these tests locally, I found a few more failures: entity_component, entity_platform, homee, litejet, lutron, openrgb, recorder, rfxtrx.

The few tests I have looked at seem geniune failures and Python versions <3.13.2 just hid those. We might have to go integration by integration to fix each.

So far, I have looked into two integrations:

Wemo (`wemo`)

Wemo fails a few tests, e.g.

FAILED tests/components/wemo/test_switch.py::test_available_after_update - AssertionError: assert 'off' == 'unavailable'

Looking at the wrapper:

    @contextlib.contextmanager
    def _wemo_call_wrapper(self, message: str) -> Generator[None]:
        """Wrap calls to the device that change its state.

        1. Takes care of making available=False when communications with the
           device fails.
        2. Ensures all entities sharing the same coordinator are aware of
           updates to the device state.
        """
        try:
            yield
        except ActionException as err:
            _LOGGER.warning("Could not %s for %s (%s)", message, self.name, err)
            self.coordinator.last_exception = err
            self.coordinator.last_update_success = False  # Used for self.available.
        finally:
            self.hass.add_job(self.coordinator.async_update_listeners)

It seems with the change in asyncio.futures._chain_future, if a test calls:

    await hass.services.async_call(
        domain,
        SERVICE_TURN_ON,
        {ATTR_ENTITY_ID: [wemo_entity.entity_id]},
        blocking=True,
    )
    assert hass.states.get(wemo_entity.entity_id).state == STATE_UNAVAILABLE

awaiting the service call doesn't guarantee that the entity has already changed, since the callback added to the event loop self.hass.add_job(self.coordinator.async_update_listeners) does not run after the coroutine anymore. It will instead run the next time the event loop processes its _ready queue. If we add a await hass.async_block_till_done() the test passes again. But I think the proper solution is to make sure that when the service call returns, the entities are all updated by rewriting the wrapper a bit.

Home Assistant Cloud (`cloud`)

The cloud integration tests (test_google_entity_registry_sync, test_do_not_create_repair_issues_at_startup_if_not_logged_in, test_create_repair_issues_at_startup_if_logged_in) fail with asyncio.exceptions.InvalidStateError: invalid state during test teardown on Python 3.14.3.

These tests set up the cloud component via mock_cloud(), which loads the cloud TTS platform. TTS depends on ffmpeg, so the ffmpeg component runs ffmpeg -version as a subprocess.

In theory, we have a session-scoped fixture prevent_ffmpeg_subprocess in tests/components/conftest.py that's supposed to mock this subprocess away, but its activation condition is find_spec("ffmpeg") is not None (#121628). This checks for a Python module named ffmpeg, which doesn't exist — the actual package is haffmpeg (installed as ha-ffmpeg). So the fixture was never active, and real ffmpeg subprocesses were always being spawned. -> This should be adressed in a seperate PR.

Why the test fails (creating a subprocess shouldn't be an issue - it just makes the test slow) is still not quite clear to me. The tracelogs point to asyncio/base_subprocess.py / _try_finish() so it might be a bug in cpython itself.

CI now passes - but do we want this merged just before beta?
Or should we/could we jump straight to 3.14.4?

Please note that there might be some remaining flaky tests. The frequent ones have been exposed by all the test runs but there are probably some rarer ones lurking about.

Discussed it with Frenck and it's okay from his side, if we create a nightly afterwards. I created a PR. Let's hope that the CI is not failing. Also I build a test image. If all looks fine, we can merge it and I will create a nightly afterwards, which I will test on the green
