It looks like the closing curly brace is in the wrong place. The following
should work (I tend to use call instead of cast, but I think they're
equivalent in this case):

send_message(Channel, Host, Password, Message) ->
    amqp_channel:call(Channel,
        #'basic.publish'{exchange = <<"">>, routing_key = <<"test">>},
        #amqp_msg{payload = Message}
    ).
