free_port()

Determines a free port using sockets.

find_connectable_ip(host, port=None)

Resolve a hostname to an IP, preferring IPv4 addresses.

We prefer IPv4 so that we don’t change behavior from previous IPv4-only implementations, and because some drivers (e.g., FirefoxDriver) do not support IPv6 connections.

If the optional port number is provided, only IPs that listen on the given port are considered.

Args:
  • host - A hostname.
  • port - Optional port number.
Returns:

A single IP address, as a string. If any IPv4 address is found, one is returned. Otherwise, if any IPv6 address is found, one is returned. If neither, then None is returned.

join_host_port(host, port)

Joins a hostname and port together.

This is a minimal implementation intended to cope with IPv6 literals. For example, _join_host_port(‘::1’, 80) == ‘[::1]:80’.

Args:
  • host - A hostname.
  • port - An integer port.
is_connectable(port, host="localhost")

Tries to connect to the server at port to see if it is running.

Args:
  • port - The port to connect.
is_url_connectable(port)

Tries to connect to the HTTP server at /status path and specified port to see if it responds successfully.

Args:
  • port - The port to connect.
keys_to_typing(value)

Processes the values that will be typed in the element.
