Testing Patterns

Lupin uses a three-tier testing strategy for comprehensive validation.

Test Tiers Overview

Tier	Location	Speed	Purpose	Run Command
Unit	`src/tests/unit/`	1-10ms	Isolated functions	`pytest src/tests/unit/`
Smoke	inline `quick_smoke_test()`	10-100ms	Module sanity	`python -m cosa.rest.jwt_service`
Integration	`src/tests/integration/`	100-1000ms	End-to-end flows	`./src/tests/run-integration-tests.sh -v`
WebSocket	`src/tests/websocket_smoke/`	varies	WS functionality	`src/scripts/run-websocket-smoke-tests.sh`
Live Pipeline	`src/tests/smoke/test_*_live_pipeline.py`	10-120s	Full LLM pipeline	`python src/tests/smoke/test_calculator_live_pipeline.py`
UI E2E	`src/tests/e2e/`	5-30s	Browser-level UI flows	(Planned v0.1.6)
