How you can Integrate Selenium Grid With Docker

Using its eminent features, it’s effectively supplying a number of advantages towards the teams. Particularly with Selenium Grid, teams can run tests in parallel and distribute tests across several virtual machines. Also, by integrating Selenium Grid with Docker, teams can efficiently run distributed applications faster if you take up less space than Virtual Machines.

Selenium is an extremely popular automation framework and broadly liked by many teams due to its suite of tools for example Selenium IDE, Selenium RC, Selenium WebDriver, and Selenium Grid. Of these, Selenium Grid is effectively benefitting development teams to operate tests in parallel on multiple systems or machines. Also, by configuring Selenium Grid with Docker, the procedure is becoming more effective and faster in running distributed applications having a limited quantity of space being occupied.

Configuring with Docker is usually the smartest choice when compared with virtual machines. But, you may still find a couple of enterprises that actually work with virtual machines. This really is due to the fact they do not know the advantages and feel integration is complicated with Docker.

What’s Selenium Grid?

Selenium Grid is among the major tools of selenium that’s effectively employed for running selenium tests parallel as well as for disbursing tests across multiple virtual machines. To operate tests in parallel using the selenium grid, it is important to configure the selenium grid with Nodes and Hubs.

Hub may be the primary point where test demands are received combined with the needed configurations and abilities. Based on the received request, the hub distributes the exam cases between your registered nodes.

The majority of the enterprises utilize virtual machines for executing these selenium scripts. But, the disadvantage from the virtual machines is the fact that in line with the quantity of scripts, the node machines need to get integrated. And, this leads to issues within the Grid atmosphere while establishing browsers and OS combinations.

What’s Docker?

Docker could be much much like a container. It’s an open platform utilized by system managers and developers. These Docker users can put databases, libraries, and dependencies in to these containers and then utilize them for building, deploying, and running distributed applications. Although it is frequently known as costly and time-consuming, Dockers efficiently solve time-consuming and price-related issues.

How you can integrate Selenium Grid with Docker?

1.Before intending to integrate Selenium Grid with Docker, it is important to install some prerequisites in your machine, for example:

•           Selenium Web Driver Jars

•           Chrome and Mozilla Firefox browsers set up in the device

•           JDK v1.7

•           To enable parallel testing, result in the parallel flag true in TestNG.xml

•           Have test cases which are developed in TestNg and Selenium Web Driver

1.After meeting the needs, install the Docker. After it’s correctly installed, have to install hubs and nodes for integrating, i.e. needed to set up the hub and node images in to the Docker. Consider five images for example Selenium hub image, selenium node-firefox image, selenium node-chrome image, selenium node-firefox-debug image, and selenium node-chrome-debug image.

2.Next, these images need to be located on the Docker Hub. Search the pictures and you will see numerous image repositories. Of these, choose the image that’s getting the greatest quantity of pulls.

3.A window is going to be opened up having a Docker pull command which works well for installing the Docker image within the container. Continue exactly the same one at a time to obtain the Docker pull command for those images and download it in to the container.

4.Now, for beginning selenium hub from Docker container, utilize a special command for example docker run -d -p 4444:4444 -name selenium-hub selenium/hub and also the Selenium hub is going to be directly opened up in the Docker Container.

5.Now, utilize both chrome node and Firefox node after which Chrome debug node and Firefox debug node. Refresh the browser, and Firefox and Chrome can get began in the container.

6.Now, find out the port figures of chrome debug nodes and Firefox debug nodes to begin both browsers using Virtual Network Computing viewer.

7.Finally, create selenium test scripts and run these to begin to see the different browsers produced through Docker.

Conclusion:

The above mentioned-pointed out information completely information regarding Selenium Grid, Docker, and also the steps to integrate the selenium grid with Docker. Although the steps tend to be simpler , leverage automation testing services from next-gen QA testing services provider to offer the complete benefits using the Selenium Test Automation framework.
