E2E Tests

Purpose

Generate end-to-end tests using Jest + Testcontainers for real PostgreSQL, Redis, and RabbitMQ instances with proper setup, teardown, and tenant isolation testing.

Why Jest Instead of node:test?

This repository uses Jest for ALL testing instead of Node.js's built-in node:test runner:

• Issue: nestjs/nest#14130 - NestJS @nestjs/testing is incompatible with node:test
• Impact: node:test cannot properly inject QueryBus, CommandBus, or other NestJS providers
• Solution: Jest provides full compatibility with NestJS's testing utilities and DI system

Note: These are E2E tests that test the entire application stack. For module-level integration tests with co-located test fixtures, use test-integration.
