Introduction
Have you ever worked with any testing software? Or Do you know what Selenium is?
This article is focused on a testing framework named Selenium. In detail, we will discuss one of the components of Selenium (Selenium Grid) and how it helps to execute our scripts on a remote machine.
Let’s dive into the blog to explore more about Selenium Grid.
What is Selenium?
Selenium is an open-source framework used for testing. It is used to automate the actions of the product. Selenium allows you to write test scripts in various programming languages while automating a web browser to behave like a user. Programming language includes Java, Ruby, PHP, Python, C#, NodeJS, etc. Selenium-based tests are ideal for testing for different versions of web browsers. It is also suitable for testing different types of the web browser.
There are four main components of the Selenium project. They are as follows:-
Selenium RC
Selenium IDE (Integrated Development Environment)
Selenium Grid
Selenium WebDriver
What is Selenium Grid? Why is it Used?
Selenium Grid is based on a client-server architecture. 'Hub' is the client, and the server is a 'Node .''Selenium Grid' is created when they are combined.
When you set up an online Selenium Grid, it will allow you to run Selenium test automation for any combination of browsers. It allows running test automation for operating systems and their versions too. Grid is used to perform testing on different browsers like Chrome, Microsoft Edge, Firefox, Internet Explorer, Safari, etc. It is platform-agnostic. It means a source code written for Linux will work smoothly on other operating systems like macOS, Windows, etc. Selenium Grid also brings in parallel testing and distribution during Selenium test automation.
Now, you should have understood what the selenium grid is. Let's know some of the advantages of Selenium Grid.
Advantages of Selenium Grid
When you start programming in a particular language, you find learning challenging. But once you gain experience, you become more comfortable with the language. This is also applicable to a test framework. Adapting to a new programming language is not hard with more experience. But you might need to spend more time-solving issues and debugging that comes after development. This is the point where a test framework like Selenium scores high.
Given below are the advantages of using Selenium test automation for a web application:
It has Extensive Language Support.
It has Dedicated Framework Support.
It has Multi-Browser Support.
It has Multi-Operating System Support.
It is Free and open source.
It allows Parallel Test Execution (Local and Cloud-Based).
It gives powerful reporting for Test Progress Tracking.
It has Integration with CI/CD Pipeline.
It can be used for Android &iOS Mobile Apps Testing.
It allows you to reuse code for Improved Maintenance.
It has a Vibrant Developer & Support Community.
It has Keyboard & Mouse Simulation.
It updates the product timely.
It allows Optimum Hardware Usage.
It enables the Automation of Browser Interactions.
There is No External Server Requirement.
It has Cloud-Based Selenium Test Automation.
Execution on Remote Machines
Now, after understanding the Selenium Grid and its advantages. Let's know how we can execute scripts on remote machines.
You can execute your scripts using Selenium Grid on remote machines with the help of Katalon Studio. Follow the following steps to set up your remote execution using Selenium Grid:
Open Katalon Studio
Navigate to Project > Settings > Desired Capabilities > Remote. Enter the information given below:
Remote Server URL: It is the URL to the remote server. It is in the format of http://<hub-ip-address>:<port>/wd/hub. For example, http://192.168.39.45:45339/wd/hub.
Remote Server type: select Selenium.
To add desired capabilities for remote execution, Click Add. This step is optional. All Selenium Server desired capabilities are supported by Katalon Studio.
Save your settings by clicking Apply and Close.
Select Remote in the dropdown list of the Run button.
Frequently Asked Questions
Is Selenium a Java or Python?
Selenium test automation framework can be done with various programming languages like Java, Python, C#, Ruby, etc.
Which language is best for Selenium?
Selenium supports various programming languages for executing test automation. But, the best languages for binding with Selenium are Java and Python.
Does Selenium require programming?
Yes, Selenium requires coding skills to carry out testing processes.
Is selenium Grid a tool?
Selenium Grid is a tool that distributes tests across multiple physical or virtual machines. It helps to execute scripts in parallel (simultaneously). It accelerates the testing process across platforms and browsers by giving accurate and quick feedback.
