swagger-test

Specification-driven REST API testing tool that validates HTTP responses against Swagger/OpenAPI specifications. Version 0.8.0 is the latest stable release (as of 2016+), with no active maintenance. It offers both CLI and programmatic usage, supports explicit x-amples extension and automatic inference of test cases. Unlike broader API testing frameworks (e.g., Postman, Dredd), swagger-test focuses purely on Swagger spec conformance with no built-in HTTP client.
