bench-rest

bench-rest is a Node.js library (v1.2.4, no recent release) for load-testing REST APIs using a declarative DSL. It combines request, async, and measured to define REST flows with setup/teardown, token substitution, and concurrency control. Metrics include latency, throughput, and error counts. Last updated around 2016; works with Node >=0.10. Simpler than artillery but limited to HTTP(S); no WebSocket support.
