How can I test async functions in Python?

You can use the pytest library along with pytest-asyncio to test async functions. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

import pytest
import asyncio

async def async_function():
    await asyncio.sleep(1)
    return 'Hello, World!'

@pytest.mark.asyncio
async def test_async_function():
    result = await async_function()
    assert result == 'Hello, World!'

What if I want to test multiple async functions?

You can define multiple test functions using the same @pytest.mark.asyncio decorator for each async function you want to test.
