* TST-012: Security Test Suite (CC-046)
|
||||
*
|
||||
* HTTP-level security tests via NestJS TestingModule + supertest.
|
||||
* Covers: SEC-003 (authentication), SEC-004 (tenant isolation guards),
|
||||
* helmet headers, CORS enforcement, route enumeration safety,
|
||||
* CASL agent tool registry policy.
|
||||
* Self-contained: uses a minimal stub guard to simulate real auth behavior
|
||||
* without importing SessionGuard (which pulls in drizzle/pg at module level).
|
||||
*
|
||||
* DB and Supabase are mocked — no real connections needed.
|
||||
* JWT verification uses the real jose/GoTrue path but without a valid
|
||||
* SUPABASE_JWT_SECRET, so any bearer token throws UnauthorizedException.
|
||||
* Tests cover:
|
||||
* - SEC-003: Authentication enforcement (401 on missing/invalid token)
|
||||
* - Helmet security headers
|
||||
* - CORS origin whitelist enforcement
|
||||
* - Route enumeration safety (404 not 500, no stack leaks)
|
||||
* - CASL agent tool registry policy (unit, no HTTP)
