Zombie.js 是一个node.js环境下，非常小巧高效率的Web UI Automation Test库.本文将介绍如何使用Zombie.js对Web UI进行自动化测试.
本文使用到的环境:
快速预览Zombie.js测试
const Browser = require('zombie');
Browser.localhost('example.com', 3000);
describe('User visits signup page', function() {
const browser = new Browser();
before(function(done) {
browser.visit('/signup', done);
});
describe('submits form', function() {
before(function(done) {
browser
.fill('email', 'zombie@underworld.dead')
.fill('password', 'eat-the-living')
.pressButton('Sign Me Up!', done);
});
it('should be successful', function() {
browser.assert.success();
});
it('should see welcome page', function() {
browser.assert.text('title', 'Welcome To Brains Depot');
});
});
});
Zombie.js适用场景
好的方面
Zombie.js与传统的Selenium和PhandomJS不同，它不会启动真正的浏览器，使得测试运行效率媲美单元测试。 Zombile.js默认采用mocha风格编写测试，无需再为WebDriver做额外的配置,如果你熟悉mocha, Zombie.js将是开箱即用的库.
Features
- 模拟浏览器行为
- Assertions, 可以采用jQuery的Selector对dom进行assert
- Cookies
- Ajax & WebSocket
限制
由于Zombie.js没有真正启动传统的WebDriver, 因此过于复杂的场景将会无法测试. 例如，如何对高德地图经测试，我还没有找到好的方法.
安装Zombie.js
npm install -g mocha
npm install zombie --save-dev
由于本文使用coffeescript代替javascript, 还需要安装coffeescript环境
npm install -g coffee-script
编写第一个测试
Brower = require 'zombie'
Brower.localhost('yourdomain.com', 5000)
describe 'User visits login page', () ->
browser = new Brower()
before (done) ->
browser.visit '/login', done
describe 'submits login form', () ->
before (done) ->
browser
.fill 'username', 'xxxx@mail.com'
.fill 'password', 'password'
.pressButton('登录', done)
it 'should be successful', () ->
browser.assert.success()
it 'should visit admin page', () ->
browser.assert.url /^http:\/\/yourdomain\.com\/users\/\d\/admin/
it 'should see profile button with email', () ->
browser.assert.link('#profile-button', 'xxxx@mail.com', '#')
运行测试:
- 开启你的web server
- 运行测试
mocha --harmony --compilers coffee:coffee-script/register login_spec.coffee
由于Zombie.js使用到了ECMA 6,需要使用 --harmony 参数开启 node.js 对ECMA 6语法支持.
使用Gulp.js构建Build Pipeline
通常我们会讲自动化测试加入到build pipeline中. 这里将介绍将 Express.js + Zombie.js + gulp.js的配置方法.
Build pipeline策略
- checkstyle, 检查代码格式
- 运行unit test
- compile coffeescript -> javascript
- 启动server
- 运行automation test
- 出错或者结束测试，停止server
由于gulp-develop-server无法用coffeescript启动server,所以需要添加compile步骤.
express.js项目结构组织
├── acceptence-test // automation test代码
│ ├── admin_spec.coffee
│ └── login_spec.coffee
├── app //后台app代码 coffeescript
├── bin
├── config
├── dist //coffeescript编译后的js代码
├── gulpfile.coffee
├── gulpfile.js
├── node_modules
├── package.json
├── public
├── spec // unit test代码
│ ├── activities_spec.coffee
│ ├── auth_spec.coffee
│ └── projects_spec.coffee
└── views
安装依赖
npm install -g gulp
npm install gulp-mocha gulp-coffee gulp-coffeelint gulp-sync gulp-task-listing gulp-develop-server harmonize --save-dev
- harmonize: 使gulp支持ECMA 6
- gulp-develop-server: 用于启动node.js connect based Web Server
- gulp-sync: 用于同步运行tasks
- gulp-task-listing: 为gulp.js添加help支持， 可以列出gulpfile中的所有tasks.
配置gulpfile
require("harmonize")()
gulp = require 'gulp'
gulpsync = require('gulp-sync')(gulp)
server = require 'gulp-develop-server'
coffeelint = require 'gulp-coffeelint'
mocha = require 'gulp-mocha'
karma = require 'gulp-karma'
coffee = require 'gulp-coffee'
task_listing = require('gulp-task-listing')
gulp.task 'help', task_listing.withFilters null, 'sync'
gulp.task 'coffee:lint', ->
gulp.src(['app/**/*.coffee', './*.coffee'])
.pipe(coffeelint('config/coffeelint.json'))
.pipe(coffeelint.reporter())
.pipe(coffeelint.reporter('fail'))
gulp.task 'coffee:compile', ['coffee:lint'], ->
gulp.src ['app.coffee', './app/**/*.coffee']
.pipe coffee()
.pipe gulp.dest('./dist')
gulp.task 'test:unit', ['coffee:lint'], ->
gulp.src('spec/**/*.coffee')
.pipe(mocha(reporter: 'spec'))
gulp.task 'test:ui', ['coffee:compile'], ->
server.listen path: './dist/app.js'
gulp.src('acceptence-test/**/*.coffee')
.pipe(mocha(reporter: 'spec'))
.on 'error', () -> server.kill()
.on 'end', () -> server.kill()
gulp.task 'test', gulpsync.sync(['test:unit', 'test:ui']), ->
gulp.task 'clean', ->
console.log 'clean task...'
gulp.task 'default', ['clean'], ->
gulp.start 'test'
运行测试
gulp test:ui
运行结果
[11:03:21] Starting 'coffee:lint'...
[11:03:22] Finished 'coffee:lint' after 184 ms
[11:03:22] Starting 'coffee:compile'...
[11:03:22] Finished 'coffee:compile' after 114 ms
[11:03:22] Starting 'test:ui'...

由于已经将test:ui加入到default task中. 直接运行 gulp 便可运行所有测试.
