One File to Rule Your API Docs and Tests

This article highlights the common problem of drift between API documentation (OpenAPI specs) and testing tools like Postman collections. It proposes a solution: embedding test scenarios directly into the OpenAPI spec, making it both documentation and executable test suite. By unifying these into a single source of truth and using a lightweight Go-based tool, developers can reduce maintenance overhead, improve CI efficiency, and ensure API behavior always matches its specification.
