def client_sends_binary(self, message, name=None, label=None):
client, name = self._clients.get_with_name(name)<EOL>client.send(message)<EOL>self._register_send(client, label, name)<EOL>
Send raw binary `message`.

        If client `name` is not given, uses the latest client. Optional message
        `label` is shown on logs.

        Examples:
        | Client sends binary | Hello! |
        | Client sends binary | ${some binary} | Client1 | label=DebugMessage |
