How can I test async APIs using Python?

You can use libraries like httpx or aiohttp to test async APIs in Python. Would you like a code example?

Yes, please provide a code example using httpx.

Sure! Here's a simple example:

import httpx

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

# Usage
import asyncio

url = 'https://api.example.com/data'
result = asyncio.run(fetch_data(url))
print(result)

What if I want to test multiple endpoints at once?

You can use asyncio.gather to run multiple requests concurrently. Here's how:

async def fetch_multiple(urls):
    async with httpx.AsyncClient() as client:
        responses = await asyncio.gather(*(client.get(url) for url in urls))
        return [response.json() for response in responses]

# Usage
urls = ['https://api.example.com/data1', 'https://api.example.com/data2']
results = asyncio.run(fetch_multiple(urls))
print(results)
