Cross Browser Testing with virtualization includes relating and analyzing the function of your website in different browser environments. It helps assure that your website delivers an optimal user experience, independent of the browser used to access it.

What is Cross Browser Testing?

Cross Browser testing is a type of non-functional testing that lets you verify whether your website operates as expected when accessed through:

Distinct Browser-OS combinations i.e., on modern browsers like Firefox, Chrome, Edge, Safari—toward any of the modern operating systems like Windows, Mac OS, iOS and Android.

Distinctive methods i.e., users can view and interact with your website on popular devices—smartphones, tablets, desktops and laptops etc.

Assistive Tools i.e., the website is compatible with assistive technologies like screen readers for differently-abled individuals.

It’s about transportation releases that are as browser-agnostic as desirable, which is key to achieving a consistent user involvement on a diverse, ever-growing range of browsers/devices.


Why is Cross Browser Testing Important?

Think that you’re attempting to reach a site that archives IOT enabled device image. Let’s assume you’re doing it for the first time from your first ever MacBook Air.

You open Safari, type the URL, press Enter, and wait for it to load. When it does, none of the Images are loading. Buttons and text are all over the page. You check your connectivity and reload, just to see the same screen.

In the end, you’ll likely do one of two things–assume that the site has an issue and leave to return later, or feel that the site is broken and leave to discover an alternative.

Browser vendors follow Open Web Standards, but they have their interpretations of it. Since they each render HTML, CSS, and JavaScript in unique ways.

Completely debugging your website’s source code is not sufficient to guarantee that your website will look and perform as expected on different browsers (or various versions of a single browser).

So it comes to web developers to abstract browser differences. Cross browser testing helps with that by pinpointing browser-specific compatibility errors so you can debug them quickly.

It helps ensure that you’re not separating a meaningful part of your target viewers–simply because your website does not work on their browser-OS.

Why is cross browser testing needed?

Cross browser testing as explained beforehand is performed to test the application’s adaptability with various browsers. Some of the other frequent reasons for doing cross-browser testing are:

  • To find bugs in the applications and be able to correct them.
  • To improve user-experience beyond every browser.
  • To improve the performance of the app
  • To detect any feasible drawbacks
  • To test if the app seems identical over different browsers.
  • To verify if all the functionalities of the app work excellent on various browsers.
  • To check if it achieves the client’s specifications over all the browsers.
  • To confirm if all the functionalities of the app work fine on various browsers.
  • To check if it meets the client’s requirements across all the browser

Who Does Cross Browser Testing?

A Tester is responsible to do this but only on the operational level. As business analysts, clients, stakeholders have an evenly critical role in determining the number and names of the browsers the testing must be focused on.

The analyst team and the clients create a listing of the various regularly used browsers by the application end-users and testers then execute testing across it.

Cross Browser Testing with Virtualization:

Virtualization is a process that enables you to virtually access computer hardware, storage devices, and computer network resources.

It is right to say that virtualization has converted a lifeline for big and small businesses when it comes to reducing the testing resources with many systems or browsers.

By leveraging virtualization, companies can save both time and money over their release cycles.

As per Capgemini, “Virtualization is the foundation for cloud computing and IT-as-a-service, any organization transitioning to the cloud needs to virtualize the majority of its environment – at least 70% including business-critical applications.” 

Today, everyone is taking their business online. We have online portals for every service enabling everyone to display their business over the internet. 

What Happens You Virtualize Software Testing?

So now, the question is how does virtualization help software testing?

While doing web testing, a tester requires to test the software on all the potential combinations of memory, OS, browsers, and browser versions.

Doing this with the actual hardware will not be pleasant as it will add up to the company’s cost and manual drills. Virtualization provides a feasible solution by providing the tester environment where they can actually test the software on all possible configurations on a single hardware system.

Testers can quite quickly customize the system according to their specifications for different configurations. This not only improves the tester to test in various environments but also to protect the actual hardware system from inherent bugs and crashes.

If the virtual system crashes, it will not affect the actual system, and within a few minutes, a new virtual environment will be created.


How Virtualization in Software Testing Benefits You?

Virtualization can effectively reduce man-hours and increase efficiency if properly applied to software testing. It gives the following advantages to software testing:

  • Server Compression
  • Disaster Rescue
  • High Availability
  • Less Complexity
  • Secure Data
  • Time-Saving
