If someone had given you software a decade ago and asked you to test it on all OS and browsers available, you would have chosen just one technique. Install hundreds of PCs with various operating systems, browsers, and browser versions, and then test the program.
However, because of advances in the information technology industry and software, this process has been greatly simplified. Virtualization is one such technology that enables you to test applications on a localized platform.
What Exactly Is Virtualization?
Virtualization is a method of accessing computer hardware, storage devices, and computer network resources remotely. Virtualization has undoubtedly become a lifeline for both large and small businesses. Companies can save money and time by utilizing virtualization during their release cycles. Virtualization is the cornerstone for cloud computing and IT-as-a-service. Any firm shifting to the cloud must virtualize at least 70% of its environment, including business-critical applications.
Instead of using the real version, virtualization creates a virtual version of any operating system, storage, server, network, network resources, or desktop. Imagine a whole separate operating system running inside your PC. You may use virtualization to create a system with the RAM, OS, browser, and other characteristics you need on your hardware. Operating system virtualization enables a single piece of hardware to run many operating systems at the same time while keeping the hardware ignorant of the virtualization.
Everyone is doing business online nowadays. We have B2B, B2C, and C2C online portals that allow anyone to represent their business on the internet. The initial impression is always essential, and when it comes to your business, your website is the first thing your clients notice. Nobody wants to tamper with that.
As a result, web testing for browser compatibility, like virtualization, has become an essential part of every release cycle. However, you might be wondering what function virtualization plays in cross browser testing.
What Happens When Testing Is Virtualized?
So, how can virtualization assist software or cross-browser testing? A web tester must test the software on all possible combinations of memory, OS, browsers, and browser versions when performing web testing.
It will be unpleasant to do this with actual hardware because it will increase the company's costs and require hand drills. Virtualization is a viable approach since it gives the tester with an environment in which they can test the program in all possible configurations on a single hardware machine.
For various configurations, testers can quickly adapt the system according to their specifications. This improves the tester's ability to test in a variety of environments while also protecting the actual hardware system from flaws and crashes.
If the virtual system crashes, it will not affect the actual system, and a new virtual environment will be built within a few minutes.
Lambda Test is a popular cross-browser testing solution that requires no installation and employs virtualization on cloud infrastructure to provide access to the testing platform. You can perform automated testing of websites and web apps on over 3000 browsers and OS that includes capabilities like screenshots, local testing, responsive design testing, APIs, and more.
Techniques For Virtualization
Virtualization is a vast subject. Your solutions and infrastructure may be segmented and virtualized at numerous points. The most common sorts of virtualization methods you'll come across in everyday life are:
When a tester takes on a testing project, they go through a set of procedures that include setting up a test environment, testing the application, and reporting the findings. This process takes time. You may argue that a tester should spend the majority of their time testing rather than setting up a test environment, configuring it, or generating backup files and settings.
However, the tester must ensure that the infrastructure is working smoothly so that files are not lost in the event of a system breakdown. But what if we construct a virtual environment that automatically produces backup files, and in the event that the system fails, the virtual environment produced on the real hardware fails instead of the actual operating system? Desktop virtualization is the process of creating a virtual desktop or environment on a physical computer.
Importance Of Virtualization For Cross Browser Testing
If properly utilized in the development and testing process, virtualization technologies may significantly cut man-hours and boost process efficiency. Virtualization in software testing, in particular, provides the following advantages:
The difference between these two kinds is that linked cloning is instantaneous, and the produced virtual machine relates to its 'father.' All modifications performed in the clone are reflected in the 'parent' clone, and vice versa. The entire cloning procedure takes significantly longer than the linked cloning since it produces a new, independent virtual computer.
Due to the flexibility of virtual machine hardware configurations, testing conditions may be easily produced (RAM memory space, limitation of resources, number of virtual processors).
Benefits Of Virtualization
Virtualization the following advantages for software testing:
Limitations of Virtualization For Cross Browser Testing
Despite the benefits of virtual testing environments, there are several limitations to be aware of:
Wrapping-Up!
Based on the information shown so far, we can infer that employing virtualization in software testing benefits as it cuts the time spent setting up test user environments and configuring test environments in half.
When development team members and product consumers have public access to identified bugs, bug detection and problem fixing become more successful. For various sorts of testing, virtual test infrastructure is one of the finest ways to improve the efficiency of the development process while also making team interaction easier.
