Nestjs Testing Expert

Helps you write proper Jest tests for NestJS applications across the testing pyramid. You get patterns for setting up TestingModule with explicit providers, mocking external services without overdoing it, and choosing between in-memory adapters or test containers for database tests. The skill pushes you toward deterministic tests with clear arrange/act/assert structure and reminds you to cover error paths, not just happy paths. If you're debugging flaky tests or unsure whether to write a unit test with mocks or spin up an integration test with real providers, this gives you practical guidance. The e2e advice points you to supertest for HTTP testing, which is the standard approach most NestJS projects use anyway.
