I have a mongo class for my fastAPI application:
`
from motor.motor_asyncio import AsyncIOMotorClient
from config import settings
import asyncio

class Mongo:
def init(self):
client = AsyncIOMotorClient(
host=settings.MONGO_HOST,
port=settings.MONGO_PORT,
username=settings.MONGO_USER,
password=settings.MONGO_PASS,
authSource=settings.MONGO_DB,
retryWrites=False
)

    db = client[settings.MONGO_DB]
    
    self.services_col = db["services"]
    self.access_keys_col = db["access-keys"]
    self.categories_col = db["categories"]
    self.roles_col = db['roles']

    self.collections = {
        "services": self.services_col,
        "access-keys": self.access_keys_col,
        "categories": self.categories_col,
        "roles": self.roles_col
    }

async def create_indexes(self):
    # Create indexes on the services collection
    await self.services_col.create_index("name")
    await self.services_col.create_index("dashboardPath")
    
    # Create indexes on the categories collection
    await self.categories_col.create_index("name")
    await self.categories_col.create_index("dashboardPath")

mongo_instance = Mongo()`

I Also have some async tests to test my APIs:

This is the conftest.py:
`
import pytest
import asyncio
import pytest_asyncio
from httpx import AsyncClient
from clients.mongo import mongo_instance

 @pytest.yield_fixture(scope="session")
 def event_loop(request):
    """Create an instance of the default event loop for each test 
    case."""
    loop = asyncio.get_event_loop_policy().new_event_loop()
    yield loop
    loop.close()

`

And these are some tests for example:

`
import pytest
from httpx import AsyncClient
import pytest_asyncio
import asyncio
from tests.utils import *

 @pytest.mark.asyncio
 async def test_add_service(async_client):
     await remove_entity('test_category', 'categories')
     await remove_entity('test_service', 'services')

     current_services = await count_entities('services')

`

The problem is I don’t know how to add indices to the Mongo instance since add index needs await, and if I do await on that on my application, I will get event loop closed on my tests as well and even without tests my API does not work in Swagger.

Thanks

I tried adding await to create index function or changing conftest but did not work
