Fact Summary

• Dependency Injection with Pydantic V2: To prevent DI containers from receiving complex instances instead of primitive config dicts, enforce mode='json' during config dumps: container.from_dict(config.model_dump(mode='json')). Eliminate legacy _orig_from_pydantic shims.
• Pydantic V2 Nested Root List Validation: When migrating/handling legacy dictionary payloads like {"root": [...]} for lists, define the model as RootModel[list[AnySegment]] and use @model_validator(mode='before') to seamlessly parse the legacy structure.
• Pytest/OpenTelemetry Shutdown Crashes: To prevent ConsoleSpanExporter stdout flush crashes during Pytest teardown, conditionally disable the flush by checking the environment: if os.environ.get('PYTEST_CURRENT_TEST') is None:.
• Async Mocking: Always use AsyncMock (not MagicMock) for awaited dependencies to prevent TypeError: object MagicMock can't be used in 'await' expression.
• PlayAI/httpx testing: When testing httpx clients with retry mechanisms, ensure mock assertions correctly account for the timeout parameter and handle potential retry jitter in mock_sleep.
