Pull request overview
This PR improves the test suite’s resource hygiene by adding automatic cleanup of transport- and client-owned aiohttp sessions, preventing ResourceWarning: unclosed ... warnings and reducing the chance of session leaks across async tests.
Changes:
- Added per-module
autousefixtures to track created transport instances and close them during teardown. - Added an
autousefixture intests/test_httpclient.pyto close anyHttpClientinstances created by tests. - Replaced several unclosed
aiohttp.ClientSession()usages intests/test_deviceconfig.pywith a shared fixture that ensures sessions are closed.

@rytilahti Ok, here is a much better handling for the tests and the httpclient.py sessions and clients. |
Add a single autouse fixture in tests/conftest.py that tracks all BaseTransport and HttpClient instances via __init__ monkeypatching, then closes them after each test. Uses functools.wraps to preserve original __init__ signatures so existing inspect-based tests continue to pass.

Summary
Add a centralized autouse fixture in
tests/conftest.pythat automatically tracks and cleans up allBaseTransport,HttpClient, andaiohttp.ClientSessioninstances created during tests. This prevents resource leaks (unclosed sessions/transports) from polluting test output with warnings.Changes
