Unittest with server.handle_exit(sig=signal.SIGINT, frame=None) fails due to KeyboardInterrupt

[HenningDinero]

I'm trying to write a unittest for a PR I'm making.

I do struggle on how to test some-signal handling. The following test raises a "KeyboardInterrupt" error

import asyncio
import signal

import httpx
import pytest

from tests.utils import run_server
from uvicorn import Server
from uvicorn.config import Config

@pytest.mark.anyio
async def test_true(unused_tcp_port: int):


    async def accept_request_app(scope, receive, send):
        await send({"type": "http.response.start", "status": 200, "headers": []})
        await send({"type": "http.response.body", "body": b"some body", "more_body": False})

    async def make_request():
        async with httpx.AsyncClient() as client:
            req = asyncio.create_task(client.get(f"http://127.0.0.1:{unused_tcp_port}"))
            return await req

    config = Config(app=accept_request_app, reload=False, port=unused_tcp_port)
    server: Server

    async with run_server(config) as server:
        await asyncio.sleep(0.1)
        await make_request()
        server.handle_exit(sig=signal.SIGINT, frame=None)  # exit
        await asyncio.sleep(0.1)

I assume it is due to await server.shutdown() in test.utils run_server that creates a force-exit since a SIGINT has been raised already.

The test passes if the last sleep is removed.
