nestjs-testing

The skill content is coherent with its stated purpose: it provides a structured blueprint for writing NestJS tests (unit, integration, e2e) following Sellernote conventions, and it emphasizes proper test layering, mocking, and validation. There are no evident security or data-flow risks in the described workflow, and dependencies would be expected to come from official registries or local monorepo setups. The footprint is proportionate to its testing-focused objective, with no credential exposure or supply-chain concerns evident from the material provided.
