Tests for each integration are stored inside a directory named after the integration domain. For example, tests for the mobile app integration should be stored intests/components/mobile_app.

The content of this folder looks like this:

• __init__.py: Required forpytest to find the tests, you can keep this file limited to a docstring introducing the integration tests"""Tests for the Mobile App integration.""".
• conftest.py: Pytest test fixtures
• test_xxx.py: Tests testing a corresponding part of the integration. Tests of functionality in__init__.py, for example setting up, reloading and unloading a config entry, should be in a file namedtest_init.py.

Sharing test fixtures with other integrations​

If your integration is an entity integration which other integrations have platforms with, for examplelight orsensor, the integration can provide test fixtures which can be used when writing tests for other integrations.

For example, thelight integration may provide fixtures for creating mocked light entities by adding fixture stubs totests/components/conftest.py, and the actual implementation of the fixtures intests/components/light/common.py.
