Should You Be Doing More API Testing?
28 Apr 2023
Peter Thomas is CTO, Co-Founder of Karate Labs and the original creator of the Karate open-source framework adopted by 650+ companies including 76 of the Fortune 500, with over two million monthly downloads and 8,800+ GitHub stars. Karate is featured in the Gartner Market Guide for API & MCP Testing Tools (March 2026) and is embedded as the foundation of Guidewire’s own API testing framework, making Karate Labs Guidewire’s first and sole testing technology partner.
His current work is Karate Agent, an AI-native verification platform built on the architecture this talk teaches: an LLM-driven agent explores systems and drafts tests and candidate business rules, while a deterministic verification layer (with no model in the decision path) grades every claim against product-owner-approved rules and computes a ship verdict with requirement-level traceability. The platform is self-hosted and BYO-LLM by design, and runs in production across banking, insurance, and financial services.
Peter speaks internationally on test architecture, API design, and the engineering of trustworthy agentic systems.
