How can I test async APIs in Python?

You can use libraries like httpx or aiohttp along with pytest to test async APIs in Python.

Can you show me a simple example using httpx?

Sure! Here's a basic example:

import httpx
import asyncio

async def fetch_data(url):
    async with httpx.AsyncClient() as client:
        response = await client.get(url)
        return response.json()

async def main():
    data = await fetch_data('https://api.example.com/data')
    print(data)

asyncio.run(main())

What about testing with pytest?

You can use pytest with pytest-asyncio to test async functions. Here's a quick example:

import pytest
import httpx

@pytest.mark.asyncio
async def test_fetch_data():
    data = await fetch_data('https://api.example.com/data')
    assert data is not None
