Refactor tests in GIOS #155756

mik-laj · 2025-11-03T19:58:51Z

Proposed change

This refactoring makes the tests mock the whole Gios object instead of individual methods, as requested in https://github.com/home-assistant/core/pull/155603/files#r2483768993. I also created fixtures for tests to reduce duplication.

It is not needed here.

-    ):
-        flow = config_flow.GiosFlowHandler()


This looked weird to me, so I used the hass.config_entries.flow.async_init method that creates this object.

This doesn't look like a test of our code, but a test of the gios library.

I checked this again and it was reason of decrease of test coverage.

Pull Request Overview

This PR modernizes the GIOS integration test suite by refactoring it to use modern pytest fixtures and patterns instead of manually loading JSON fixtures and patching API calls. The changes improve test maintainability and align with current Home Assistant testing best practices.

Key changes:

Introduces a centralized conftest.py with reusable fixtures (mock_gios, mock_config_entry, init_integration)
Replaces JSON fixture files with in-code test data using gios.model dataclasses
Migrates tests to use modern mocking patterns with MagicMock and cleaner setup/teardown
Adds freezegun for time-based testing instead of manual time manipulation

Here it is also necessary to prove that recovery flow after an error is possible.

Why patch PLATFORMS if the integration only supports the SENSOR platform?

This is old code and I extended it to cover the entire module.
