socket.io/eventEmitter 單元測試與回歸測試 #17
Description
目的
我近期在建立一個關於socket.io應用的專案（類似聊天室），最近要做單元測試和回歸測試
使用的工具
我在 windows 7 下使用 npm 安裝 node.js v6.2.1,
socket.io v1.4
unittest 套件
mocha, should
操作流程
為了做socketIo的單元測試，我做了以下操作：
describe('unittest', () => {
before('init', () => {
//init
});
it('eventEmitter listen', ()=>{
emitter.on('someEvent', (receiveObj) => {
should(receiveObj).have.property('name', 'userName');
});
});
it('server site', () => {
socketIo.sockets.on('connection', function(socket) {
//socket listeners
});
});
it('client site', () => {
var jsonObj = ...//initialized
client.on('connect', function() {
setTimeout(() => {
client.emit('client_event', jsonObj);
}, 300 * delay);
});
});
});
遇到的問題
Microsoft Windows [版本 6.1.7601]
Copyright (c) 2009 Microsoft Corporation. All rights reserved.
D:....event_handler>mocha competeLockTest.js
unittest: CompeteLockEventHandler
server site: event handlers
√ client site:
1 passing (116ms)
註解: 其實他甚麼都沒有檢查到!!!!!!!!!!!!!! 連client送到server site的event都沒監聽到，eventEmitter也沒聲沒息
嘗試過的解法
我嘗試過把結構改成
describe('unittest', () => {
describe('xxx', () => {
it('eventEmitter listen', (){...} )
it('server site' (){...} )
it('client site' (){...} )
})
})
程式碼
下面附上我的程式碼以及我遇到的"錯誤"
程式碼
const clientIo = require('socket.io-client');
var socketURL = 'http://127.0.0.1:1337';
var serverIo = socketIo.listen(Server);
var password = '0000';
var createRoomInfo_A = {uid: 'Terrence0503',
roomName: 'Top Secrit',
pwd: password };
var createRoomInfo_B = {uid: 'Leo3355687',
roomName: 'Nice Club',
pwd: password };
var uid_A = 'Terrence0503', userA = { uid: uid_A, objCode: '0001', },
uid_B = 'Sziyu321654', userB = { uid: uid_B, objCode: '0001', };
function funcCreateRoom(client, createRoomInfo, delay) {
should(createRoomInfo).have.property('uid');
should(createRoomInfo).have.property('roomName');
should(createRoomInfo).have.property('pwd');
client.on('connect', function() {
setTimeout(() => {
client.emit('create_room', createRoomInfo);
}, 300 * delay);
});
}
describe('unittest: Create Room', () => {
before('init', () => {
//init variables...
});
it('eventEmitter listen', () => {
emitter.on('messageEvent', (receiveObj) => {
shoud(receiveObj).have.property(‘name’, ‘userName’);
….
});
});
it('server site: event handlers', () => {
serverIo.sockets.on('connection', function(socket) {
socket.on('create_room', function(jsonObj) {
shoud(jsonObj).have.property(‘name’, ‘userName’);
….
createRoomEventHandler.handle(socket, jsonObj);
});
});
});
it('client site: ', () => {
var len = users.length;
var clients = [];
for(var i = 0; i < len; i++) {
var client = clientIo.connect(socketURL);
clients.push(client);
}
var interval = 1;
funcCreateRoom (clients[0], createRoomInfo_A, interval++);
});
});

他至少應該要在打勾的地方出現我用should/assert測試的語句，但其實他甚麼都沒有檢查到!!!!!!!!!!!!!! 連client送到server site的event都沒監聽到，eventEmitter也沒聲沒息。
