node-testing

Overall, the skill footprint is coherent with a Node.js backend testing focus. It uses standard testing libraries and patterns (integration tests, authentication tests, testcontainers for real DB tests, and E2E flows). There are no evident credential harvesting or deceptive data flows. Security risk is low to moderate due to handling of tokens and secrets in test contexts; ensure logs do not leak secrets and that test containers are properly scoped to CI environments.
