What are some examples of using pytest-asyncio?

Can you provide some examples of using pytest-asyncio for testing?!

Sure! pytest-asyncio is a plugin for pytest that allows you to test asynchronous code. One example is testing an async function that fetches data from an API.

How would I write a test for an async function using pytest-asyncio?

You can use the @pytest.mark.asyncio decorator to mark your test function as asynchronous. Here's a simple example:

import pytest
import asyncio

async def fetch_data():
    await asyncio.sleep(1)
    return 'data'

@pytest.mark.asyncio
def test_fetch_data():
    result = asyncio.run(fetch_data())
    assert result == 'data'

What if I want to test multiple async functions?

You can write multiple test functions, each marked with @pytest.mark.asyncio, or you can use asyncio.gather() to run them concurrently within a single test.

Are there any best practices for using pytest-asyncio?

Yes! Some best practices include keeping your tests isolated, using fixtures for setup, and avoiding blocking calls in your async tests.
