Where is a complete example of testing with pytest using Quart's extension Quart-OpenAPI?

Question

I'd like to use pytest with Quart's extension quart-openapi, but the documentation examples and googling have not helped.

Where can I find a concrete, example of the pytest testing tool being used with quart-openapi?

So far I've read through these sources:

Quart's blog tutorial with testing

Quart documentation on testing

Stack Overflow question on similar tools

The project structure is:

├── app
│   ├── __init__.py
│   ├── api.py
│   ├── log.py
│   
├── requirements.txt
├── run.py
└── tests
    ├── __init__.py
    └── test_endpoint.py

app/__init__.py:


    from .api import QUART_APP

api.py:


    """Registered endpoints"""
    from quart import jsonify
    from quart_openapi import Pint, Resource

    # Docs say that Pint will forward all init args to Quart()
    QUART_APP = Pint(__name__, title="Quart tts")

    @QUART_APP.route('/')
    class Home(Resource):
        """ Endpoint that reports its own status """
        async def get(self):
            """ Report status of service """
            return jsonify({'OK': True, 'hello': 'world'})

test_endpoint.py:


    import pytest
    from app.api import QUART_APP as app
    @pytest.fixture(name='test_app')
    def _test_app():
        return app

    @pytest.mark.asyncio
    async def test_app(app):
        client = app.test_client()
        response = await client.get('/')
        assert response.status_code == 200

Actual results: ERROR at setup of test_app ... fixture 'app' not found

Expected results: I'm able to test with quart-openapi using pytest.

Looking at the pytest fixture docs the name you give the fixture is the name you would reference. So I'd probably change the "name" param to be 'testapp' like so:

import pytest
from app.api import QUART_APP as app
@pytest.fixture(name='testapp')
def _test_app():
  return app

@pytest.mark.asyncio
async def test_app(testapp):
  client = testapp.test_client()
  response = await client.get('/')
  assert response.status_code == 200

When I set this up in my own directory the above works and passes so it should work for you.
