+## Testing Framework
+- AIDEV-NOTE: Successfully migrated from Ward to pytest (2025-06-24)
+- All test files now use pytest conventions (test_* functions)
+- Fixtures centralized in conftest.py with pytest_asyncio for async tests
+- S3 client fixture fixed for async event loop compatibility using AsyncExitStack
+- Usage cost tests updated to use dynamic pricing from litellm
+- All Ward imports removed, migration complete
+- Run tests: `poe test` or `poe test -k "pattern"` for specific tests
+- Stop on first failure: `poe test -x`
