As the name suggests, Cross Browser Testing (CBT) is a process to perform tests on multiple browsers. This is done to know how a website performs on different browsers. Cross-Browser testing gives the confidence that the website behaviour is consistent across various browsers. CBT just not tests the performance of the website on different platforms but also checks the UI behaviour on these platforms.

There are many ways that a website can fail in front of the audience, but cross-browser issues should not be one of them. The performance of your website adds up to the success of it.

Since technology has advanced so much, the internet is available to many people today. This number has increased quite significantly for mobile users since mobile has become an important part of life. Easy internet access has increased browser usage on desktop and mobile platforms. For this, cross-browser testing becomes an important process before launching a website. But, cross-Browser testing comes at a cost. Therefore, not every website goes through this testing.

For example, you would not need to have a government examination application website go through this process. You can simply add a disclaimer to open the website in a particular browser. Since you need to fill the form somehow, the customers will open it however possible. This is not the case with the website where it is not necessary to open it. For example, a website that lets you download songs. You would want your customers to have a seamless experience whether they browse your website on Android or iOS. If I sum it up, you need to get your website tested.

Why Cross Browser Testing is needed?

In olden days, there used to be only a handful of browsers existing across the internet, and they were mainly situated on desktops. Additionally, with a waterfall model design process where developers were primarily making quarterly or monthly changes to code, manually testing each one was relatively simple.

Now time have changed, however, and today’s consumers are on a multitude of devices ranging from desktop computers and laptops to mobile phones and tablets, while there are too many browsers and browser versions to count at this point. Furthermore, to parallel the rise of mobile and desktop internet consumption, design and development have moved to an agile methodology. Developers are no longer making yearly updates but instead instituting continuous integration with updates by the hour or day.

Meanwhile, each browser responds to these code changes differently, and so with every change of code comes a risk that any of those browser/device/OS combinations may not respond according to expectations. Layout, accessibility, connectivity, quality, and performance can vary slightly or exponentially from browser to browser, as each renders CSS, HTML, and JavaScript differently.

Developers inherently know and learn the lowest risk browsers and devices, and in turn, use them every day to view the product of their coding. However, a misconception is that another user will be visiting the same website on the same browsers and devices. “It works on my machine” is not a valid argument.

While about half of users will be on the popular, low-risk browsers that developers use such as Chrome and Firefox, the bugs will mainly be saturated in high-risk browsers like Internet Explorer. You could direct a user who’s experiencing issues on a bugged browser to either update their browser version or download different browser altogether, but it’s more likely that user will be unwilling or unable to switch browsers just to properly view your website. Instead, they’ll just leave your page.

Though it may be unrealistic to test 100 percent of all browser platforms, it’s important to create an acceptable user experience amongst the majority of your user base. The more browsers that are tested and optimised, the more inclusive your site will be for a variety of visitors. This is not to say that each should look exactly the same, but instead that there is an element of responsive design that has been implemented and tested.

Things to take care during testing!

  • The first thing that needs to be done is to decide how many browsers you want to test on and which ones
  • You have to decide whether to test on a real physical devise or a desktop or a mobile emulator.
  • Need to decide the way of test execution – Manual or Automation.
  • Consider Base Functionality and Graphical User Interface based functionality during the testing.

Tesbo can help you test functionality of your web application on different Web Browsers. It ensures compatibility of your application on different Web browsers like Internet Explorer, Firefox, Safari, Chrome etc at same time. You can create test on any one Web browser and run it on different Web browsers and this way test application’s behaviour on different browsers without need to re-creation of test on multiple browsers.
