Selenium grid implementation on two different machines and browsers

This post guides us for the GRID implementation of Selenium where we launch a grid server and register two nodes in two different machines.

Here we launch the HUB in machine1 and start node 1 with two instances of chrome browser and node 2 with two instances of Firefox.


To start Hub

HUB: Machine 1

java -jar selenium-server-standalone-2.43.1.jar -role hub -port 4455

To start nodes

Node : Machine 2 (launching only chrome browser of 2 instances)
 

java -jar selenium-server-standalone-2.43.1.jar -role node -hub http://<ip_of_hub_machine:4455>/grid/register -port 5557 -Dwebdriver.chrome.driver=chromedriver.exe -browser browserName=chrome,platform=WINDOWS,maxInstances=2

Node: Machine 3 (launching only firefox browser of 2 instances)

java -jar selenium-server-standalone-2.45.0.jar -role node -hub http://<ip_of_hub_machine:4455>/grid/register -port 5587 -browser browserName=firefox,platform=WINDOWS,maxInstances=2

After launching hub and nodes we can see the instances of the nodes in grid console under URL http://localhost:4455/grid/console

 
Sample program:

import java.net.MalformedURLException;
import java.net.URL;
import java.util.concurrent.TimeUnit;

import org.openqa.selenium.Platform;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;

public class GridTest {

    static DesiredCapabilities dc = null;
    WebDriver driver;

    public GridTest() throws MalformedURLException {
        dc = new DesiredCapabilities();
       

    }

    public void firefox() throws MalformedURLException, InterruptedException {
        dc.setBrowserName(DesiredCapabilities.firefox().getBrowserName());
        excute("firefox");
    }

    public void chorme() throws MalformedURLException, InterruptedException {
        dc.setBrowserName(DesiredCapabilities.chrome().getBrowserName());
        excute("chrome");
    }

    public void excute(String browsername) throws MalformedURLException, InterruptedException {
       
        dc.setPlatform(Platform.WINDOWS);
        driver = new RemoteWebDriver(new URL(
                "http://<ip_of_hub_machine:4455>/wd/hub"), dc);
        driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
        System.out.println("In "+browsername);
        driver.get("https://www.google.co.in/");
        System.out.println(driver.getCurrentUrl());
        driver.quit();
    }

    public static void main(String[] args) throws MalformedURLException, InterruptedException {
        // TODO Auto-generated method stub

        GridTest t1 = new GridTest();

        t1.firefox();
        t1.chorme();

    }
}

Firefox in Machine 1

Chrome in Machine 2
