Why It Matters

For engineers building multi-agent systems with A2A, this fills a critical gap in testing inter-agent communication, delegation correctness, and fault tolerance—areas that standard chat or API tests ignore.

Key Takeaways

Adopt tamesu's `a2a` target to simulate untrusted or failing downstream agents and validate your agent's protocol compliance and error handling before production.

Testing A2A Agents with tamesu: Tasks, Delegations and Agents You Cannot Trust

Summary

tamesu, an open-source Go CLI, introduces an `a2a` target for testing agents using the Agent2Agent (A2A) protocol. It validates agent cards, task lifecycles, and delegations by simulating both the user and backend agents, including failure and hostile response scenarios. A practical test suite for a Genkit Go concierge agent demonstrates catching issues like a lying shipping agent or a down billing service that chat-level tests would miss.
