## role
Documents a completed test infrastructure modernization initiative that restructured a backend API project's testing into unit/integration/system tiers with multi-database support and E2E coverage.
## files
- .openspec.yaml | Defines an OpenSpec configuration file with schema type and creation date metadata
- design.md | This file documents the design and migration plan for restructuring a test suite into unit, integration, and system categories with shared fixtures, SQLite/PostgreSQL separation, and E2E coverage. | dep: pytest, pytest-asyncio, SQLite, PostgreSQL, Playwright, Docker, React/Vite, asyncpg, pytest-xdist
- proposal.md | Proposes a comprehensive restructuring of test infrastructure to separate unit/integration/system tests, add shared fixtures, enable SQLite for unit tests, implement transaction rollback isolation, and introduce Playwright E2E testing. | dep: pytest, PostgreSQL, SQLite, Playwright, python-jose, docker, Makefile
- tasks.md | Project task list tracking completed testing infrastructure improvements for a backend API project including test restructuring, shared fixtures, multi-database support, E2E setup, and documentation. | dep: pytest, pytest-asyncio, SQLAlchemy, aiosqlite, PostgreSQL, Playwright, python-jose, TestClient, Makefile
## arch
Specification-driven change management using OpenSpec metadata with design-proposal-tasks workflow; test architecture follows layered pyramid pattern (unit/SQLite, integration/PostgreSQL, system/E2E with Playwright) employing shared fixtures and transaction rollback isolation.
