Question

我在AmazonEC2上运行了Selenium Grid

它由在端口7055上运行的集线器和在端口7056上运行的节点组成。

我有以下测试：

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。

连接到网格集线器时出现的错误是：

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

我的问题是： Selenium WebdriverJS是否支持连接到集线器？如果是这样，我做错了什么？

注意：

我已连接到集线器并成功运行与rspec测试相同的步骤。
我还能够在EC2实例上本地连接到集线器并运行测试，只有在尝试远程连接到网格时才会发生。
在7055 / grid / console查看Selenium2网格控制台时，它似乎确实在节点上使用会话。

我在EC2上用来启动网格的命令：

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webdriver？我没有使用JS驱动程序，但C＃有一个特定的远程网格连接驱动程序。

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

查看JS文档，在构造驱动程序时可能需要执行以下操作：

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

在Selenium Grid上运行WebdriverJS测试
