How do I test async views in Django?

To test async views in Django, you can use the pytest framework along with pytest-asyncio. This allows you to write async test functions.

Can you show me a simple example of an async view and its test?

Sure! Here's a simple async view:

from django.http import JsonResponse

async def my_async_view(request):
    return JsonResponse({'message': 'Hello, async world!'})

And the test would look like this:

import pytest
from django.urls import reverse

@pytest.mark.asyncio
async def test_my_async_view(client):
    response = await client.get(reverse('my_async_view'))
    assert response.status_code == 200
    assert response.json() == {'message': 'Hello, async world!'}

What if I want to test an async view that interacts with a database?

You can use Django's database fixture in your tests. Just make sure to use pytest.mark.asyncio to handle the async nature. Here's an example:

@pytest.mark.asyncio
async def test_my_async_view_with_db(client, db):
    # Create a test object in the database
    await MyModel.objects.create(name='Test')
    response = await client.get(reverse('my_async_view'))
    assert response.status_code == 200
    assert response.json() == {'message': 'Hello, async world!'}
