javascript - Testing socket.io with Zombie.js across two browsers -

-

i'm building real time chat app using node , socket.io. having problems trying feature test using zombie. app working fine in browser test failing message

assertionerror: expected '' include 'hello'

during debugging seems when zombie presses send button not fire 'chat message' event - though in development.

describe('chat feature', function() {      beforeeach(function(done) {      browser1 = new browser({        site: "http://localhost:3000"      });      browser2 = new browser({        site: "http://localhost:3000"      });      done();    });      beforeeach(function(done) {      browser1.visit('/', done);    });      beforeeach(function(done) {      browser2.visit('/', done);    });      describe("chat page has been rendered", function() {      beforeeach(function(done) {        browser2.pressbutton('javascript testing');        browser2.fill('.chatbox-input', 'hello');        browser2.pressbutton('send', done);      });      it('sends chat messages between browsers', function(done) {        expect(browser1.text('li')).to.contain('hello');        done();      });    });  });

and html (dynamically loading scripts content div using jquery)

<html>    <head>    <title>global code network</title>    <link rel='stylesheet' href='/stylesheets/style.css' />  </head>    <body>      <div class="main">      <h1>global code network</h1>      <div id="content"></div>    </div>      <div class="bottom-bar">      <h2>current requests:</h2>      <div id="join-rooms"></div>    </div>      <script id="chat-template" type="text/template">      <ul id="messages"></ul>      <form id="chatbox" action="">        <input type="text" class="chatbox-input" id="m" name="chat-input" autocomplete="off" />        <input type="submit" value="send"></input>      </form>    </script>    <script id="end-chat-template" type="text/template"></script>    <script src="/socket.io/socket.io.js"></script>    <script src="http://code.jquery.com/jquery-1.11.1.js"></script>    <script src="/scripts/main.js"></script>  </body>  </html>

client side js 

(function(exports) {      var socket = io();        socket.on('person joined', function(data) {      $('.bottom-bar').remove();      $('#content').html($('#chat-template').html());      $('#chatbox').submit(function(e) {        e.preventdefault();        socket.emit('chat message', {          roomid: data.roomid,          message: $('#m').val()        });        $('#m').val('');      });      socket.on('chat message', function(data) {        $('#messages').append($('<li>').text(data.message));      });    });      exports.socket = socket;    })(this);

and server side js

io.on('connection', function(socket) {    socket.on('join room', function(data) {      socket.join(data.roomid);      io.to(data.roomid).emit('person joined', {        roomid: data.roomid      });        socket.broadcast.emit('update available rooms', {        rooms: rooms      });    });      socket.on('chat message', function(data) {      io.to(data.roomid).emit('chat message', data);    });  });

thanks

Android volley - avoid multiple requests of the same kind to the server? -

-
i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response
