Autonomous Testing Agent
An autonomous testing agent operates with minimal human direction — setting sub-goals, executing multi-step plans, and adapting its approach based on results — the most independent end of the AI test agent spectrum, distinguished from simpler tools that still need a human to define each specific step.
The distinguishing feature is genuine autonomy in planning, not just execution — given a broad goal, an autonomous agent breaks it down into sub-tasks itself, decides an order of operations, and adjusts that plan based on what it discovers along the way, rather than executing a fixed sequence a human already fully specified.
This level of autonomy raises the stakes on evaluation and oversight — an agent making its own decisions about what to test next and how needs clear boundaries on what actions it's permitted to take, and thorough logging of its reasoning and actions, so a human can review and trust (or correct) what it actually did.
