So I'm seeing an error in the logs that I suspect must be the cause of the
test failures:

  "mod_pywebsocket: web_socket_transfer_data raised exception for /ws/echo: Connection read error"

The full error message is this attached.

I'm trying to troubleshoot it now. I'll let you all know if I make any

Do any of these actually require a websocket connection (such a test would have something like var ws = new WebSocket(SCHEME_HOST_PORT + "/ws/foo") in the source)? A number of the tests don't have any actual server-side requirement. Does adding ?wss to the url make a difference? That will use encrypted websockets over port
