运行硒网格WebdriverJS测试

Question

我有硒网格上AmazonEC2运行

它包括在端口7055上运行的轮毂和端口上运行的节点的7056

我有以下试验：

var webdriver = require('selenium-webdriver'), 
    driver = new webdriver.Builder(). 
     usingServer('http://ec2-50-18-75-182.us-west-1.compute.amazonaws.com:7055/wd/hub'). 
     withCapabilities({'browserName': 'firefox'}). 
     build(); 


var postTitle = "Post "+(+new Date); 

driver.get('http://si-demo.herokuapp.com/posts/new'); 
driver.findElement(webdriver.By.id('post_name')).sendKeys("Selenium"); 
driver.findElement(webdriver.By.id('post_title')).sendKeys(postTitle); 
driver.findElement(webdriver.By.id('post_content')).sendKeys("This is auto generated by a test"); 
driver.findElement(webdriver.By.name('commit')).click(); 
driver.quit(); 

当我尝试连接到集线器端口时失败。 当我直接连接到节点端口时，测试会运行。

连接到电网枢纽，当我得到的错误是：

timers.js:103 
      if (!process.listeners('uncaughtException').length) throw e; 
                    ^

我的问题是： 不硒WebdriverJS支持连接到集线器？如果是这样我做错了什么？

注：

• 我已经连接到轮毂并成功运行的相同步骤一个RSpec测试。
• 我也能够在EC2实例上本地连接集线器并运行测试，只有在尝试远程连接到电网时才会发生。
• 当在Selenium2网格控制台上查看：7055/grid/console时，它似乎在节点上使用会话。

命令我在EC2上用于启动电网：

Xvfb :0 -screen 0 1024x768x24 2>&1 >/dev/null & 
export DISPLAY=:0 
java -jar selenium-server-standalone-2.32.0.jar -port 7055 -role hub 
xvfb-run java -jar selenium-server-standalone-2.32.0.jar -role node -hub http://localhost:7055/grid/register

您是否尝试过使用远程的webdriver？ 我没有使用JS驱动程序，但C＃有一个远程电网连接的特定驱动程序。

https://code.google.com/p/selenium/wiki/WebDriverJs#Using_the_Stand-alone_Selenium_Server

望着JS文件，你可能需要在构造你的驱动程序做这样的事情：

var webdriver = require('selenium-webdriver'), 
    SeleniumServer = require('selenium-webdriver/remote').SeleniumServer;
