我已经写了一个socket.io服务器，我正在用mocha它来测试它。但是我第二次无法连接到服务器。
这是我的代码，它是由咖啡脚本编写的。
服务器：
server = require('http').Server()
io = require('socket.io').listen(server)
io.on 'connection', (socket) ->
console.log socket.id
server.listen(3000)
测试：
chai = require 'chai'
io = require 'socket.io-client'
should = chai.should()
describe 'Socket', ()->
url = 'http://0.0.0.0:3000'
it 'should be connected', (done) ->
client = io.connect(url)
client.on 'connect', (data) ->
console.log(data)
client.socket.connected.should.equal(true)
client.disconnect()
done()
describe 'User', ()->
url = 'http://0.0.0.0:3000'
it 'should be connected', (done) ->
client = io.connect(url)
client.on 'connect', (data) ->
console.log(data)
client.socket.connected.should.equal(true)
client.disconnect()
done()
服务器输出：
