Testing agents and tools

When to use

Writing tests for code that builds AG2 beta Agents, custom @tool functions, middleware, or response schemas — anywhere you don't want to make real LLM API calls.

60-second recipe — mock an LLM response

import pytest
from autogen.beta import Agent
from autogen.beta.testing import TestConfig

@pytest.mark.asyncio
async def test_mocked_response():
    agent = Agent("test_agent")
    reply = await agent.ask("Hi!", config=TestConfig("This is a mocked response."))
    assert reply.body == "This is a mocked response."
