Hurley: A High-Performance HTTP Client and Load Testing Tool Engineered in Rust

Introduction and Motivation This article examines the technical architecture, capabilities, and use cases of hurley, a project developed in Rust that functions as both a general-purpose HTTP client and a performance testing tool. It explores the efficiency advantages gained by managing API testing and performance analysis through a unified tool within software development processes. With the proliferation of microservices architectures and distributed systems, communication via the HTTP protocol has become the lifeblood of the software ecosystem. In this context, developers face two fundamental needs: (1) A flexible HTTP client to verify the functional correctness of API endpoints, and (2) Performance testing tools to analyze system behavior under load.
