GRID setup tutorial.

Hi Guys,

I have done selenium grid setup on 5 different node which contains 2 LINUX and 3 Windows node. I would like to share the setup information to reduce the R&D time on that, which is totally frustrating . But not any more, It's just a simple example of working setup and feel free to modify as per your requirement.

Pr-requisite:

1. download selenium standalone server on hub machine and setup Java also on all machines.
   
2. download all the browser drivers which you want to supported on node and placed in a common directory.
   
3. All machine should be on same network group otherwise you will have to do some effort to resolve the network and firewall issues.
   

Hub setup:
java -jar selenium-server-standalone-2.52.0.jar -role hub -port 4441


Node's setup:
java -jar selenium-server-standalone-2.52.0.jar -role webdriver -browser browserName=chrome -browser browserName=firefox -browser browserName="internet explorer" -hub [You must be registered and logged in to see this link.] -port 5566 -Dwebdriver.ie.driver=C:\Users\Advisor\Downloads\Selenium_browser_Driver\IEDriverServer_x64_2.52.2\IEDriverServer.exe  -Dwebdriver.chrome.driver=C:\Users\Advisor\Downloads\Selenium_browser_Driver\chromedriver_win32\chromedriver.exe

Make sure all nodes are successfully registered and communicate properly with hub. Now, setup your IDE for working with web driver. google it if you don't know , how to setup.

This is the java code for running your test using grid. But right now it will execute on a single node at a time. If want to execute it on all setup node at the same time. You will have to use TestNG framework parallel method to execute simultaneously.

Code:



import net.sourceforge.htmlunit.corejs.javascript.ast.SwitchCase;

import org.openqa.selenium.By;
import org.openqa.selenium.Platform;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;

Hope this will help for newbie . Best of luck for GRID.
