Cross-browser testing tools: A comparison

Reading Time: 9 minutes:

Gone are the days when web standards were a mess, with limited browser support. Well, you must have encountered an issue with the website and on calling the technical team, they tell you to try the same website in another browser. And it works pretty fine for you.

So, is it your fault or lack of your technical expertise?

The answer is “NO”.

It’s just that the website is not extensively tested with cross-browser testing tools and lacks compatibility with some browsers. Every browser interprets the information and presents it on the website in a different manner. Some browsers may lack the features you are trying to display on your website that makes your website look broken on the browser.

Just like the below example image indicates different responses of the same website. The errors of sign-up forms are different on both browsers.

 Today, the web scenario is entirely different and in fact, much better. 

All thanks to open-source cross-browser testing tools.

“Any software tool is considered as open source if you can use and modify over the original design. The open-source tools don’t have a commercial license but serves the specific purpose of testing.”

With the next-gen technologies and tools, it is now possible to make your website work perfectly on all web and mobile browsers. The users should not be restricted to use any browser to access your website. Some of the commonly used browsers include Google Chrome, Safari, Firefox, Internet Explorer, Opera.

That being the background story, let’s understand the “What, why, how, who, when, where” of cross-browser testing.

Why is Cross Browser Testing Important?

Imagine that you are trying to access a website or app from MacBook Air. You open the Safari browser and type the URL, enter, and wait for the website to load. When it gets open, none of the images and media files gets loaded. All the text and buttons are over the web page. You check for internet connectivity and reload the page on the same screen. If it still does not open, you will assume that the site has some issue or is broken.

Now, the next obvious step is to find an alternative.

This is where open-source cross-browser testing tools come into the picture. The testing process ensures that the website and apps work in a smooth and uniform manner on all the browsers and devices used by your customers –

  • Browsers – Chrome, Safari, Firefox, Microsoft Edge, Internet Explorer, Opera, etc.
  • Operating systems – Android, Windows, iOS, macOS, etc.
  • Devices – Laptop, tablet, mobile, desktop, smart TV, etc.

Here is what you need to check with cross-browser testing.

CSS and HTML validation Special characters with HTML Character encoding Page validation with and without JavaScript enabled
Ajax and JQuery functionality Font Size Page layout in different resolutions
Images and alignment Header and footer sections Page content alignment to center, LHS, or RHS
Page styles Date formats Page zoom-in and zoom-out functionality

Hence, it is required to check the performance, user interface, and overall compatibility of the applications on all these combinations. Cross-browser testing helps to provide a high-quality and consistent experience across all browsers, operating systems, and devices.

How to Perform Cross-Browser Testing?

Now we started talking. So, cross-browser testing can be performed through the manual process or automated testing methods. Let’s understand both the choices.

Manual Method

Manual testing is performed by checking the website on multiple browsers, machines, and operating systems. Then, the same test cases need to be performed again to observe the behavior of the application and report bugs. Clearly, it will lead to increased efforts, time, and investment. Moreover, it is not possible to cover many browsers.

Automated Method

This process runs the same set of test cases multiple times on different browsers. This eliminates the manual processes and repetition of tasks. This, automation method is more time and cost effective to perform automation method with ready-to-use cross-browser testing tools

Let’s explore the top tools to make cross-browser testing easier.
