As per the records, nearly 5 lakh 76 thousand websites are created everyday. This number might keep on fluctuating as we gain and lose many websites on the same day. So there are a total of 1.7 billion websites today. So from the numbers we can see the popularity and the demand of the websites. It must be ensured that all these websites work seamlessly on all the browsers. Here cross browser testing comes into the picture. On top of it, today there are different kinds of devices to receive the content. So we have to ensure that the website can be read in the frames of different shapes and sizes. This again brings us back to cross browser testing. Hence cross browser testing is extremely important and investing in a great cross browser testing tool is crucial for organisations. There are various issues that a website comes across, for example the functioning of theUI elements, the UI look and feel, performance of the website etc and hence web/mobile application testing is the solution to these issues. But as the compatibility of the web apps on different devices and browsers is important otherwise, the app might not run or there can be several issues with the UI , influencing the user experience as well. Hence cross browser testing is imperative and without it your web application testing is absolutely incomplete. So in this blog we will look at the various aspects for why web application testing is incomplete without cross browser testing.
What is Cross Browser Testing ?
One of the greatest issues QA teams come across is device fragmentation. Device fragmentation happens if an app works fine for a user using it in a new version of browser while it does not work for the user using an old version of the browser. Hence the application does not function well in older versions of browsers, hence it is not compatible with the entire range of browsers. While developing a web or mobile application, one needs to ensure that the app is is compatible with the various device browser and OS combinations and its version. Hence this way there are a number of combinations that need to be tested. Hence cross browser testing is performed wherein the application is tested with various browsers and device combinations simultaneously. Usually automated scripts are run across the various device browser combinations in parallel, hence due to parallel testing the speed of testing increases by multiple folds.
Now let’s find all the reasons why web or mobile application testing is incomplete without cross browser testing :
1. Every browser interprets differently
The browsers and its versions keep on updating and hence that affects its ability to recognise the software codes. In Fact every browser has its own way of dealing with the software codes and hence the developer needs to make necessary code changes in the website or applications while running it on various browsers. For example the pointers and x path might not be the same for firefox and chrome, as well as its different versions. Hence cross browser testing ensures to find the bugs and ensure that the app functions seamlessly across each browser
2. Device variations
Today there are different mediums of accessing content. Be it smart phone, a tab, laptop or a kindle etc, customers can access the applications over different platforms. So while designing a web application or even a mobile application, one needs to ensure that it is responsive and can work on all kinds of screen sizes. Nowadays new devices are getting released so frequently, hence we need to ensure that a web app works properly across its various versions. Hence cross browser testing is important to ensure that the app works seamlessly across various versions.
3. Enhances User Experience
If a web application or a mobile application is not compatible enough, then there is a direct effect on the UI elements. Have you ever noticed those minute differences in the UI elements, for example, the square corners of a signup box might get changed into round corners due to the incompatibility issues in the browser. These are small changes which might get overlooked. But sometimes there is a color difference due to incompatibility. For example, a browser may read #ffff for the color Yellow while the other browser might read #AAA for the same color. If this bug is not fixed there will be a change in the color and completely ruin brand guidelines of an organisation. Hence cross browser testing is crucial for a better user experience.
With web and mobile applications getting released with lightning speed, we have to ensure that it works seamlessly across all the browsers, devices and os. To ensure that the application is compatible across various platforms and browsers, cross browser testing is performed. It ensures that the apps function well and also enhance the user experience. There are many highly scalable cross browser tools available in the market. Choose the one which suits the best for your testing environment. Before planning to work on cross browser testing it is important to understand why it is important and how it can impact the website’s performance. So do have a look at the above points to understand the importance of cross browser testing.
