Listen on custom address in AsyncHTTPTestCase

[chrishaig14]

I need to run a test and listen on 0.0.0.0 to allow an external service to connect through another IP, but the default one is 127.0.0.1.

In testing.py:

def bind_unused_port(reuse_port: bool = False) -> Tuple[socket.socket, int]:
 """Binds a server socket to an available port on localhost.

 Returns a tuple (socket, port).

 .. versionchanged:: 4.4
 Always binds to ``127.0.0.1`` without resolving the name
 ``localhost``.
 """
 sock = netutil.bind_sockets(
 0, "127.0.0.1", family=socket.AF_INET, reuse_port=reuse_port
 )[0]
 port = sock.getsockname()[1]
 return sock, port

Is there a clean way of listening on 0.0.0.0 in a test?

Not currently. It's a three-line method so you could just copy it and modify as needed. Or I wouldn't mind a PR adding a keyword argument to control the address.
