package com.grid.test;

import java.net.MalformedURLException;
import java.net.URL;

import org.openqa.selenium.Platform;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.testng.annotations.Test;

public class GridDemo {

 RemoteWebDriver driver;
 @Test
 public void gridDemo() throws MalformedURLException{
  DesiredCapabilities cap = DesiredCapabilities.firefox();
  cap.setBrowserName("firefox");
  cap.setPlatform(Platform.VISTA);
  
  URL url = new URL("http://192.168.2.9:5555/wd/hub");
  
  driver = new RemoteWebDriver(url, cap);
  
  driver.get("http://google.com");
 }
}

 URL url;
 
 @Parameters({"url", "browser", "platform"})
 @Test
 public void seleniumGrid(String URL, String browserName, String platform)
   throws MalformedURLException{
  switch (browserName) {
  case "firefox":
   cap = DesiredCapabilities.firefox();
   cap.setBrowserName(browserName);
   cap.setCapability("platform", platform);
   
   url = new URL(URL);
   break;

   cap.setCapability("platform", platform);
   
   url = new URL(URL);
   break;
  default:
   break;
  }
  
  driver = new RemoteWebDriver(url, cap);
  driver.manage().window().maximize();
  driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
  
  driver.get("http://google.com");
  
  WebElement element = driver.findElement(By.name("q"));
