AIOHTTP Connector for running ASGI applications
Decision gist · record as of 2026-08-14
Yes, if you're already using AIOHTTP and testing ASGI applications. It's a low-friction, permissive-licensed tool that solves a specific problem well. The aging maintenance status (418 days since last release) is a minor concern for a stable, narrow-scope library, but monitor the repository for responsiveness if you encounter issues.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.8+; aiohttp 3.1+ must be installed.
- ASGI lifespan events are not handled—use asgi-lifespan if you need them.
- Low friction: pure Python wheel, single runtime dependency on aiohttp.

What it is and what it does
aiohttp-asgi-connector is a custom connector for AIOHTTP's ClientSession that routes HTTP requests directly into ASGI applications without requiring a running web server. It's designed to close the gap between AIOHTTP and HTTPX's testing capabilities, letting you test ASGI apps by making async HTTP calls that bypass the network stack entirely.
The connector replaces AIOHTTP's entire connection and transport layer. You instantiate it with your ASGI app, pass it to ClientSession, and then use the session normally—requests are serialized by AIOHTTP and fed directly to the app. Exceptions raised in the app propagate back to your test code. The main limitation is that if you enable chunking or compression on the ClientSession, your ASGI app must handle decompression itself, since the connector transmits requests exactly as AIOHTTP serializes them.
Use it for
- Unit testing ASGI endpoints without spinning up a test server.
- Integration testing ASGI applications in test suites where you want to avoid network overhead.
- Verifying request/response handling in ASGI middleware without HTTP transport.
- Debugging ASGI app behavior by inspecting requests and responses in-process during tests.

Install

Before you install
Low friction: pure Python wheel, single runtime dependency on aiohttp. Maintenance status is aging—last release was 418 days ago—so expect slower response to issues, though the package remains functional for its narrow use case.
Requires Python 3.8+; aiohttp 3.1+ must be installed. ASGI lifespan events are not handled—use asgi-lifespan if you need them.
License in practice
BSD 3-Clause is permissive; you can use this in commercial and proprietary projects with minimal restriction, provided you retain the license notice.
