The cherry-picked model_picker test installed its own discord mock at
module-import time via a local _ensure_discord_mock(), overwriting
sys.modules['discord'] with a mock that lacked attributes other
gateway tests needed (Intents.default(), File, app_commands.Choice).
On pytest-xdist workers that collected test_discord_model_picker.py
first, the shared mock in tests/gateway/conftest.py got clobbered and
downstream tests failed with AttributeError / TypeError against
missing mock attrs. Classic sys.modules cross-test pollution (see
xdist-cross-test-pollution skill).
Fix:
- Extend the canonical _ensure_discord_mock() in tests/gateway/conftest.py
to cover everything the model_picker test needs: real View/Select/
Button/SelectOption classes (not MagicMock sentinels), an Embed
class that preserves title/description/color kwargs for assertion,
and Color.greyple.
- Strip the duplicated mock-setup block from test_discord_model_picker.py
and rely on the shared mock that conftest installs at collection
time.
Regression check:
scripts/run_tests.sh tests/gateway/ tests/hermes_cli/ -k 'discord or model or copilot or provider' -o 'addopts='
1291 passed (was 1288 passed + 3 xdist-ordered failures before this commit).
Keep Discord Copilot model switching responsive and current by refreshing picker data from the live catalog when possible, correcting the curated fallback list, and clearing stale controls before the switch completes.
