I am trying to make simple chat app using socket.io. I want to write tests (unit tests - to verify logic of server).
Manually it's working fine (via browser: http://localhost:3000/);
I don't get idea which tools/libraries to use for testing? Plz. Give me any idea how to do this?
Here is my node server code:
file: index.js
var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);
var socketCount = 0;
http.listen(3000, function(){
console.log('listening on *:3000');
});
app.get('/', function(req, res){
res.sendFile(__dirname + '/index.html');
});
io.on('connection', function(socket) {
socketCount++;
console.log('new user connected');
// Let all sockets know how many are connected
io.emit('users connected', socketCount);
socket.on('disconnect', function(){
// Decrease the socket count on a disconnect, emit
socketCount--;
io.emit('users connected', socketCount);
});
socket.on('chat message', function(msg){
// New message added, broadcast it to all sockets
io.emit('chat message', msg);
});
});
And here is my html page:
file: index.html
<html>
......
<body>
<ul id="messages"></ul>
<div class='footer'>
<div id="usersConnected"></div>
<form action="">
<input id="m" autocomplete="off" /><button>Send</button>
</form>
</div>
</body>
.....
<script>
$(document).ready(function(){
$('#messages').val('');
var socket = io();
$('form').submit(function(){
socket.emit('chat message', $('#m').val());
$('#m').val('');
return false;
});
// New message emitted, add it to our list of current messages
socket.on('chat message', function(msg){
$('#messages').append($('<li>').text(msg));
});
// New socket connected, display new count on page
socket.on('users connected', function(count){
$('#usersConnected').html('Users connected: ' + count);
});
});
</script>
</html>
Thanks.
