What problem does it solve?

Ensures NestJS endpoints work correctly end-to-end with real validation, authz/authn, transaction behavior, and database semantics that unit tests often miss.

Core Features & Use Cases

• Real DB-backed E2E runs: boot the full NestJS app and execute requests with supertest against PostgreSQL using testcontainers (preferred) or pg-mem.
• Auth + permission flow coverage: validate AuthGuard + HasPermission using an auth fixture and assert 401/403 outcomes per endpoint.
• Bilingual error shape verification: assert { vi, en } error message payloads for ZodValidationGuard-driven failures (e.g., 422) and confirm domain errors like 409 duplicates.
• Transaction rollback assertions: prove multi-table write endpoints roll back when a step fails by checking observable state after an induced error.

Quick Start

Run the E2E suite after wiring the endpoint by executing the skill’s guidance for test/setup-e2e.ts and test/jest-e2e.config.js, then invoke npm run test:e2e.
