Cross browser testing

Cross browser testing is the ‘new normal’ of the IT development world. Although there are still some who don’t do it, all the reigning websites swear by it. We, as developers, know that any kind of website dependency variation across any rendering engine will ward off our audience. Inconsistency diminishes appeal.

CBT is your website’s insurance ensuring its performance uniformity across all OS & devices without any quality glitch. A responsive web design may appease if your users are getting different outcomes but it’s not the magic bullet to curb these innate display issues experienced due to various browser choices. An overall CBT of the design process is a must for your clients to get their wilful platform access & transmute. It also eases ushering in advancements that will better the program.

As CBT has become high-priority, its efficient & fruitful implementation is the prime concern of every organization now.

As per Chatonic The key steps to approach cross-browser testing are:

  • Knowing your target audience.
  • Devising the appropriate Testing Matrix. 

The audience: Make use of tools like Google Analytics to get an elaborate idea of the market preferences. Which browsers and OSs have the most fan following? What’s the track record of similar websites as yours? Focus on the related group of consumers and monitor them thoroughly.

The browser matrix: A browser matrix is the shortlisted collection of all those browsers & operating systems plus their subsequent versions that you’ll test your website on. Employ analytical tools to calculate browser traffic and prioritize them on your list accordingly. You can also outcast any browser if certain features of your website aren’t agreeable with it. This reduces the error count.

Save Time On Manual Cross Browser Testing

Now that you’ve gotten the basic knowledge required to begin CBT, let us move on to the next step: the approach.

Cross-browser testing can be performed by two methods: manual or automated.


In manual testing, we physically check the website’s behaviour one by one on each browser from our matrix. In automated testing, we engage tools to do the same for us.

Difference Between Manual Testing and Automated Testing - Comparison Summary

Both manual and automated testing have their own specific fortes. Even though automation promises high accuracy, you cannot go for a 100% automated system.  A perfect mix of manual and automation testing is what guarantees success.

The manual practice takes the developers and testers to re-run the same test cases on multiple operating systems, various browsers using multiple machines and keep tabs on the response of the web app and locate any bugs in it. And the automated procedure does the identical job using an automation tool generally making the cross browser testing process less challenging. The repetition of test cases is best managed through automation. Deciding whether the website is working as per design, whether the typography is fine, if the text is appropriate or not is best analysed manually.

Why to Do Automated Testing? - BitbarThere are so many online tools in the market that can assist your testing tasks. These tools lay out all the browsers and operating systems in the cloud, thus you don’t have to download/install the browsers in your local system.
