Setup Async Testing

Purpose

Provide correct patterns for testing async functions in Python using pytest-asyncio, AsyncMock, and async fixtures. Ensures tests properly handle async context managers, side effects, and cleanup.

Quick Start

Most common use case:

# Testing an async function with mocked dependencies
import pytest
from unittest.mock import AsyncMock

@pytest.mark.asyncio
async def test_my_async_function():
    mock_service = AsyncMock()
    mock_service.fetch_data.return_value = {"result": "success"}
