socket.id is the same in two different sessions on localhost

[Pedroxam]

Should the socket.id be different in the two session in localhost ?

for example in normal chrome tab and private tab, this two tab must have deffrent socket id ?

Let me be clear about this, following code must send test to 1 user, but test can send in all sockets. like io.emit.

io.on('connection', function(socket){
    socket.on('test', function(data){
           socket.emit('test');
    });
});

Yes, the socket.id is unique per connection.

Yes, but in the localhost the socket.id is the same. anyway, i was able to solve this problem with replace socket.id with my users id.
