[java] Setting Remote Webdriver to run tests in a remote computer using Java

I was trying to setup remote webdriver to run my tests in remote computer, as my application is deployed to my localhost. Using Selenium RC I used host address to run those tests and it worked fine; but I'm having trouble setting up the base class using remote webdriver. I've tried the following code but it has not worked. By the way, I had selenium tests which I am migrating to remote webdriver. I tried webdriver which works fine but couldn't setup the remote webdriver for remote execution. Any help will be appreciated.

public static  String base_url = "http://localhost:8084";     
Proxy proxy = new Proxy();     
proxy.setProxyAutoconfigUrl(base_url);
DesiredCapabilities capabilities = DesiredCapabilities.internetExplorer();
capabilities.setCapability(CapabilityType.PROXY, proxy);
RemoteWebDriver driver = new RemoteWebDriver(capabilities);
selenium = new WebDriverBackedSelenium(driver, base_url);

Sample grid 2 code which works for firefox but doesn't work on IE9

String hubURL = "http://myip:4444/wd/hub";
DesiredCapabilities capability = DesiredCapabilities.internetExplorer();
//capability.setBrowserName("internet explorer");
//capability.setPlatform("WINDOWS");
//capability.setVersion("9.0.4");
WebDriver driver = new RemoteWebDriver(new URL(hubURL), capability);
driver.get("http://www.google.com");
WebElement element = driver.findElement(By.name("q"));
element.sendKeys("Cheese!");
element.submit();
driver.quit(); 

Error I was receiving when it's IE9 though I specified IE from command mode from node:

Exception in thread "main" org.openqa.selenium.WebDriverException: Error forwarding the new session cannot find : {platform=WINDOWS, ensureCleanSession=true, browserName=internet explorer, version=}

This is how I got rid of the error:

WebDriverException: Error forwarding the new session cannot find : {platform=WINDOWS, ensureCleanSession=true, browserName=internet explorer, version=11}

In your nodeconfig.json, the version must be a String, not an integer.

So instead of using "version": 11 use "version": "11" (note the double quotes).

A full example of a working nodecondig.json file for a RemoteWebDriver:

{
  "capabilities":
  [
    {
      "platform": "WIN8_1",
      "browserName": "internet explorer",
      "maxInstances": 1,
      "seleniumProtocol": "WebDriver"
      "version": "11"
    }
    ,{
      "platform": "WIN7",
      "browserName": "chrome",
      "maxInstances": 4,
      "seleniumProtocol": "WebDriver"
      "version": "40"
    }
    ,{
      "platform": "LINUX",
      "browserName": "firefox",
      "maxInstances": 4,
      "seleniumProtocol": "WebDriver"
      "version": "33"
    }
  ],
  "configuration":
  {
    "proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
    "maxSession": 3,
    "port": 5555,
    "host": ip,
    "register": true,
    "registerCycle": 5000,
    "hubPort": 4444,
    "hubHost": {your-ip-address}
  }
}

By Default the InternetExplorerDriver listens on port "5555". Change your huburl to match that. you can look on the cmd box window to confirm.

• First you need to create HubNode(Server) and start the HubNode(Server) from command Line/prompt using Java: -jar selenium-server-standalone-2.44.0.jar -role hub
• Then bind the node/Client to this Hub using Hub machines IPAddress or Name with any port number >1024. For Node Machine for example: Java -jar selenium-server-standalone-2.44.0.jar -role webdriver -hub http://HubmachineIPAddress:4444/grid/register -port 5566

One more thing is that whenever we use Internet Explore or Google Chrome we need to set: System.setProperty("webdriver.ie.driver",path);

This issue came for me due to the fact that .. i was running server with selenium-server-standalone-2.32.0 and client registered with selenium-server-standalone-2.37.0 .. When i made both selenium-server-standalone-2.32.0 and ran then things worked fine
