简介：

6.5. Node.js selenium-webdriver

6.5.1. 安装测试环境

6.5.1.1. Selenium Server

下载 Selenium Serverhttp://selenium-release.storage.googleapis.com/2.40/selenium-server-standalone-2.40.0.jar

启动 Selenium Server

java -jar selenium-server-standalone-2.40.0.jar

6.5.1.2. 安装 selenium-webdriver

CentOS 6.5

# yum install nodejs npm 
# npm -g install selenium-webdriver

默认node_modules安装在 /usr/lib/node_modules/selenium-webdriver

Ubuntu 13.04

sudo apt-get install nodejs
sudo apt-get install npm
sudo npm -g install selenium-webdriver

默认node_modules安装在 /usr/local/lib/node_modules/selenium-webdriver

不是用-g参数npm install selenium-webdriver 将会安装在当前目录下

6.5.1.3. 浏览器相关设置

远程控制Chrome参考

https://code.google.com/p/selenium/wiki/ChromeDriver下载后解压运行里面的可执行文件

var driver = new webdriver.Builder().usingServer('http://192.168.6.20:9515/').withCapabilities(webdriver.Capabilities.chrome()).build();

Firefox 使用

var driver = new webdriver.Builder().usingServer('http://192.168.6.20:4444/wd/hub').withCapabilities(webdriver.Capabilities.firefox()).build();

6.5.2. 测试例子

例 6.3. Node.js selenium-webdriver 本地测试

selenium-server-standalone 与测试脚本在同一台机器上

			
var webdriver = require('selenium-webdriver');

var driver = new webdriver.Builder().
    withCapabilities(webdriver.Capabilities.chrome()).
    build();

driver.get('http://www.google.com');
driver.findElement(webdriver.By.name('q')).sendKeys('webdriver');
driver.findElement(webdriver.By.name('btnK')).click();
driver.wait(function() {
  return driver.getTitle().then(function(title) {
    return title === 'webdriver - Google Search';
  });
}, 1000);

driver.quit();

例 6.4. NODE.JS selenium-webdriver 远程测试

从一台测试机遥控另台selenium-server-standalone

			
var webdriver = require('/usr/local/lib/node_modules/selenium-webdriver');

var builder = new webdriver.Builder().  
  usingServer('http://192.168.6.20:4444/wd/hub').  
  withCapabilities(webdriver.Capabilities.firefox());  

var driver = builder.build();  

driver.get('http://www.google.com');
driver.findElement(webdriver.By.name('q')).sendKeys('webdriver');
driver.findElement(webdriver.By.name('btnK')).click();
driver.wait(function() {
  return driver.getTitle().then(function(title) {
    return title === 'webdriver - Google Search';
  });
}, 1000);

driver.quit();

6.5.3. Unit Test

安装 mocha

npm install -g mocha

测试脚本

var assert = require('assert'),
test = require('selenium-webdriver/testing'),
webdriver = require('selenium-webdriver');

test.describe('Google Search', function() {

	test.it('should work', function() {
		//var driver = new webdriver.Builder().withCapabilities(webdriver.Capabilities.chrome()).build();
		var driver = new webdriver.Builder().usingServer('http://192.168.6.20:4444/wd/hub').withCapabilities(webdriver.Capabilities.firefox()).build();  
		driver.get('http://www.google.com');
		var searchBox = driver.findElement(webdriver.By.name('q'));
		searchBox.sendKeys('simple programmer');
		searchBox.getAttribute('value').then(function(value) {
			assert.equal(value, 'simple programmer');
		});
		driver.quit();
	});
});
