In order to start Selenium Grid (hub and nodes), we should write .bat files. You can create various helper methods for you to avoid redundancy. You can create a separate helper class for the click, sendkeys action and then you can call it in main test class. We will register node 2 with the below command in remote machine. On single machine we can have multiple nodes opened, Grid Hub decides what tests needs to routed on which node, we can’t control them, Each node should run only single type of browser, We need various driver objects for various threads to be run parallely, so create driver as ThreadLocal variable, Download “Selenium Standalone Server” from “http://www.seleniumhq.org/download/” on all 3 machines.

In the below example we will register a node in the same local machine where hub is running and other node in remote machine. Consider node as port opened on machine (loacal or remote). A user needs to configure the remote server in order to execute the tests. For example if i need to find a webelement by id then i can make separate function FindElementById(String id) { driver.findElementById(“ID”)} and then can call it in test class FindElementById(“Email”); and so on.
