Integration Test Builder

This builds out complete integration test suites for API endpoints with database interactions. You get test harness scaffolding with setup/teardown, database seeding with Prisma, and full CRUD endpoint tests that verify both HTTP responses and database state. It covers the practical stuff like transaction rollback verification, fixture management, and the arrange/act/assert pattern throughout. Useful when you need to test actual database flows rather than mocking everything out, especially for order processing, user management, or any multi-step operations where you want to confirm the database ended up in the right state. The CI-friendly approach with isolated test databases and automatic cleanup between tests is solid.
