App hangs on test

[skwzrd]

import os
import sys

sys.path.insert(0, os.path.dirname(os.path.dirname(__file__)))

import asyncio

from main import create_app
from configs import app_conf

async def test_endpoints():
    app = await create_app()
    results = []
    base_url = f'http://127.0.0.1:{app_conf.get("port")}'

    @app.before_serving
    async def startup():
        print("Starting up the app...")

    @app.after_serving
    async def shutdown():
        print("Shutting down the app...")

    await app.startup()

    for rule in app.url_map.iter_rules():
        print(rule)
    await app.shutdown()


if __name__ == "__main__":
    asyncio.run(test_endpoints())

This will print out

Starting up the app...
<all the routes>
Shutting down the app...

But it won't shut down on its own, and it hangs on that last line.

Databases were still connected... I found out which database it was by using something like

import sys
import traceback

for thread in threading.enumerate():
    if thread is not threading.main_thread():
        print(f'{thread.name=}')
        traceback.print_stack(sys._current_frames()[thread.ident])

I created this decorator for the test functions.

def close_all_dbs(func):
    @wraps(func)
    def wrapper(*args, **kwargs):
        func(*args, **kwargs)
        asyncio.run(db.pool_manager.close_pools())
        asyncio.run(db.pool_manager.close_pools())
    return wrapper
