我应该如何在mocha中测试客户端/服务器socket.io？

Question

如何正确关闭socket.io/websocket-client？ - 相关,但过时/不起作用

我正在编写一组测试来测试服务器端套接字.在github上获得了jamescarr的代码.Carr的代码基于Liam Kaufman在这里. 传入的文本墙.

这是测试方面.

ioServer = require("socket.io")
ioClient = require("socket.io-client")

chai.should()
chai.use(sinonChai)
expect = chai.expect

server = require('./testUtils/chat-server.coffee')

socketURL = 'http://localhost:5000'

options =
  transports: ['websockets']
  'force new connection':true

chatUser1 = name:'Tom'
chatUser2 = name:'Sally'
chatUser3 = name:'Dana'

describe "Chat Server", ->
  before (done) ->
    server.start 5000, done
  after (done) ->
    server.stop done

  it "Should broadcast new user to all users", (done) ->
    console.log "new user to all users"
    client1 = ioClient.connect(socketURL)
    client1.on "connect", (data) ->
      client1.emit "connection name", chatUser1
      client2 = ioClient.connect(socketURL, options)
      client2.on "connect", (data) ->
        client2.emit "connection name", chatUser2

      client2.on "new user", (usersName) ->
        usersName.should.equal chatUser2.name + " has joined."
        client2.disconnect()

    numUsers = 0
    client1.on "new user", (usersName) ->
      numUsers += 1
      if numUsers is 2
        usersName.should.equal chatUser2.name + " has joined."
        client1.disconnect()
        done()

这是服务器端.

io = null
clients = {}

module.exports = 
  start: (port, cb) ->
    io = require("socket.io").listen port, cb
    io.sockets.on "connection", (socket) ->
      console.log "server on connection"
      userName = ''
      socket.on "connection name", (user) ->
        console.log "server on connection name"
        clients[user.name] = socket
        userName = user.name
        io.sockets.emit "new user", user.name + " has joined."

      socket.on 'message', (msg) ->
        console.log "server on message"
        io.sockets.emit 'message', msg

      socket.on 'private message', (msg) ->
        console.log "server on private message"
        fromMsg =
          from: userName
          txt: msg.txt
        clients[msg.to].emit 'private message', fromMsg
  stop: (cb) ->
    io.server.close()
    cb()

出于某种原因,无论我做什么,我都会在连接上超时:

.......................

Answer 1

五天,没有答案所以:

这是我学到的.

1. 任何带有(done)签名的测试都必须调用done,否则将失败(duh).
2. 设置回调,将done呼叫置于最后一个.
3. 如果有两个连接并且它们相互作用,则将第二个连接的行为放在第一个连接的回调中.
4. 最后,在测试结束时启动"种子"连接.
