`is_ready()` reflects whether the worker's server has finished startup.

A basic sanity check. Simply run the reloader against a no-op server, and signal for it to quit immediately.

With reset_contextvars=True, each ASGI run starts with a fresh context. Non-regression test for https://github.com/encode/uvicorn/issues/2167.

A server exits with the dedicated startup-failure code when the app can't load. The multiprocess supervisor relies on `STARTUP_FAILURE` to tell a

A bad app path exits in the parent for the single-process case. Regression for https://github.com/encode/uvicorn/issues/941: the app is impor

`uvicorn.run()` imports the app before `Server.run` opens the event loop. Regression for https://github.com/encode/uvicorn/issues/941: an app who

With `--workers > 1` the parent does not import the app. Spawn-based workers re-import everything, so loading it in the supervisor only waste

A factory that builds its own SSLContext from scratch should work without ssl_keyfile/ssl_certfile.

A factory that just delegates to the default factory should produce a working server.

Test interrupting a Server that is run explicitly inside asyncio

The server should raise an exception if it sends multiple websocket.http.response.start events.

Test that lifespan.shutdown is called even when should_exit is set during startup.

1. Request is sent 2. Sigint is sent to uvicorn 3. Shutdown sequence start 4. Request is finished before timeout_graceful_shutdown=1

The factory can call the default and mutate the result (e.g., bump TLS minimum version).
