--------------------------------DOCKER INTALLATION----------------------------------------------
Step 1: We need to install docker
Go to the docker offical website https://www.docker.com/
Click on Get started button
Then Download docker as per your OS. I have used macOS for demo purpose
After downloading, Just install it.
Step 2:- Create a free account on docker website
Step 3:- Check docker installed or not successfully
Open terminal and hit following command
docker version
We will get docker info
Then hit following command to get complete info of docker
docker info
Then try to verify image
docker run hello-world
Then hit following command to get list of images exist into docker container
docker run hello-world
Step 4: Start docker application and login in.
Now we are going to create selenium grid docker demo
--------------------------------SELENIUM GRID IMAGES INSTALLATION----------------------------------------------
Step 5: First we need to install all required images
Go to the google and search docker selenium
and open first result or docker selenium url
https://github.com/SeleniumHQ/docker-selenium
Install following docker dependecies to execute Selenium Grid
Open terminal and hit following command one by one
Selenium hub docker pull selenium/hub
Selenium firefox node docker pull selenium/node-firefox
Selenium chrome node docker pull selenium/node-chrome
Selenium firefox debug docker pull selenium/node-firefox-debug
Selenium chrome debug docker pull selenium/node-chrome-debug
Then check list of images, We will get above mentioned all images in result.
Same will get in Docker desktop Application
docker images
--------------------------------START HUB AND NODE---------------------------------------------
Step 6: Now we need to start hub and node to execute script
Start hub :
docker run -d -p 4545:4444 --name selenium-hub selenium/hub
Note:- Here we can take any name
To check hub is started or not, Open browser and enter http://localhost:4545/
.
We will get hub console
Start Node for Firefox
docker run -d -P --link selenium-hub:hub selenium/node-firefox-debug
To check node started or not, Open broweser and check node into hub
Start Node for Chrome
docker run -d -P --link selenium-hub:hub selenium/node-chrome-debug
To check node started or not, Open broweser and check node into hub
--------------------------------VNC INSTALLATION TO VIEW NODE CONSOLE ----------------------------------
Step 7: To view firefox and chrome docker console, We need to download vnc and install it
https://www.realvnc.com/en/connect/download/viewer/macos/
Start vnc , enter node url
0.0.0.0:55000 chrome will start , here 55000 is assigned to chrome browser node
0.0.0.0:55001 Firefox will start , here 55001 is assigned to firefox browser node
--------------------------------SELENIUM SCRIPT----------------------------------------------
Step 8: We need to create demo automation script to execute on nodes
Create selenium script
ex. Firefox
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.testng.annotations.Test;
import java.net.MalformedURLException;
import java.net.URL;
public class ffdemo {
@Test
public void testApp() throws MalformedURLException, InterruptedException {
DesiredCapabilities cap= new DesiredCapabilities();
cap.setBrowserName(BrowserType.FIREFOX);
WebDriver driver=new RemoteWebDriver(new URL("http://localhost:4545/wd/hub"),cap);
driver.get("https://www.google.com/");
driver.findElement(By.name("q")).sendKeys("Autoamtion testing");
Thread.sleep(5000);
driver.quit();
}
}
ex. Chrome
package dockerdemo;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.remote.BrowserType;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.testng.annotations.Test;
import java.net.MalformedURLException;
import java.net.URL;
public class chromedemo {
@Test
public void testApp() throws MalformedURLException, InterruptedException {
DesiredCapabilities cap= new DesiredCapabilities();
cap.setBrowserName(BrowserType.CHROME);
WebDriver driver=new RemoteWebDriver(new URL("http://localhost:4545/wd/hub"),cap);
driver.get("https://www.google.com/");
driver.findElement(By.name("q")).sendKeys("Autoamtion testing");
Thread.sleep(5000);
driver.quit();
}
}
tetsng.xml for parallel execution
How to execute script:-
Right click on testng.xml and run as suite
--------------------------------EXECUTE SCRIPT----------------------------------------------
Step 9: Execute script , Execution will start on both console , Firefox ( 0.0.0.0:55001)
and chrome ( 0.0.0.0:55000 )
--------------------------------EXECUTION DEMO----------------------------------------------
Execution Demo
