API Integration Test

Generates integration tests for a REST endpoint that run against a real (or in-memory) server and database, covering the full request lifecycle.

Phase 1: Discovery

Extract before writing anything:

1. Framework — Express, Fastify, NestJS, Hapi? (affects how the server is spun up in tests)
2. Test runner — Jest or Vitest?
3. HTTP client — supertest, undici, native fetch? Default to supertest if Express/Fastify.
4. Auth mechanism — JWT, session cookie, API key, none?
5. Database — real DB with test instance, in-memory (SQLite), or mocked at the service layer?
6. What the endpoint does — method, path, request body shape, expected response shape
7. Existing test setup — is there already a test app factory, seed util, or DB teardown helper?

If the user pastes the route handler, extract the above directly. If not, ask.
