Pounce ships a testing helper that starts a real server in a background thread. Use it when your test needs socket-level behavior instead of direct ASGI calls. Context Manager from pounce.testing import TestServer async def app(scope, receive, send): await send({"type": "http.response.start", "status": 200, "headers": []}) await send({"type": "http.response.body", "body": b"ok"}) def test_app(): with TestServer(app) as server: assert server.url.startswith("http://") Pytest Fixture Installing bengal-pounce registers the pounce_server pytest fixture through the package entry point. def test_with_fixture(pounce_server): with pounce_server(app) as server: assert server.is_running The helper uses Pounce's normal listener, worker, lifespan, and shutdown paths, so it catches integration bugs that a direct ASGI harness would miss.
