pytest-homeassistant 0.1.3

Fixtures

• hass - Used to mock a hass instance. This is primarily useful in testing your config_flow code. Examples of it’s usage can be found in the Home Assistant tests.

from custom_components.steam_wishlist import config_flow

async def test_flow_init(hass):
    """Test the initial flow."""
    result = await hass.config_entries.flow.async_init(
        config_flow.DOMAIN, context={"source": "user"}
    )

    expected = {
        "data_schema": config_flow.DATA_SCHEMA,
        "description_placeholders": None,
        "errors": {},
        "flow_id": mock.ANY,
        "handler": "steam_wishlist",
        "step_id": "user",
        "type": "form",
    }
    assert expected == result

• aioclient_mock - Used to mock responses from homeassistant.helpers.aiohttp_client.async_get_clientsession in your test code.

You can find example usage of both of these fixtures in the Home Assistant tests directory.

Helpers

• pytest_homeassistant.async_mock - Contains all mock methods that can handle async calls.

from pytest_homeassistant.async_mock import AsyncMock
from custom_components.steam_wishlist import sensor_manager

async def test_sensormanager_async_register_component(
    hass, coordinator_mock
):
"""Test that we add listeners and referesh data if all platforms were registered."""
    manager = sensor_manager.SensorManager(hass, url="http://fake.com")
    mock_async_add_entities = AsyncMock()
    await manager.async_register_component("sensor", mock_async_add_entities)

    assert mock_async_add_entities.called is True
