Questions

What is AI agent testing?

AI agent testing checks systems where a model plans steps and calls tools or other systems to finish a task. Testers check the final outcome, each tool call, permissions and what happens when a step fails. 43 published entries state that they test AI agents.

How is an AI agent tested?

Testers run scripted and exploratory tasks against the agent and record every tool call, its inputs and its result. They check that the agent stops, asks or escalates when a step fails instead of guessing. Runs are repeated because the same task can take different paths.

How are agentic workflows and multi-agent systems tested?

Each agent is tested alone first, then the hand-offs between agents are tested with fixed scenarios. Testers trace which agent made each decision and check that context passed between agents is complete. Failure injection, such as a tool timing out, shows whether the workflow recovers.

What practices does AI agent testing usually include?

Common practices are task success checks, tool-call validation, permission and data-access tests, adversarial prompts and regression runs after each model or prompt change. Of the entries that state AI agents, 37 also state red teaming and 12 state regression testing.

What metrics are used to measure AI agent quality?

Typical metrics are task completion rate, correct tool selection, number of steps per task, cost and latency per task, and the rate of unsafe or policy-breaking actions. Results are compared across repeated runs because agent behaviour varies between runs.

What kinds of AI agents can be tested?

Vendors in this directory name customer service agents, coding and research assistants, workflow automation agents and voice agents. The coverage matrix on this page shows which testing services the listed vendors state for AI agents.
