What is Cross Browser Testing?

Cross-browser testing plays a role in the development of websites. It ensures that a website or web application functions smoothly across browsers, screen sizes, devices, and operating systems. This testing process aims to spot and fix any compatibility issues or errors that might occur when users access the website using browsers.

During browser testing developers carefully examine how a website behaves, functions, and looks on multiple platforms. This helps them identify any rendering problems to browsers ensuring that users have a consistent and enjoyable experience no matter which browser they prefer to use.

The Importance of Cross Browser Testing

Cross-browser testing is essential for several reasons:

1. Ensuring Display on Major Desktop Browsers

Given the range of available browsers, it is important to ensure that your website works correctly on all major desktop browsers. While Google Chrome holds the majority market share with over 64% other popular browsers, like Internet Explorer, Edge, Safari, Firefox, and Opera still have a user base.

To retain visitors effectively it is crucial to provide a user experience across all used browsers. Failing to do so may lead to a user experience resulting in reduced engagement and potential loss of customers.

2. Making Sure Your Website Works Well on Mobile Devices

In today’s mobile-centric world, it is essential to ensure that your website is compatible with various mobile browsers. Many internet users exclusively browse the internet using their handheld devices, making mobile browser testing a crucial aspect of cross-browser testing.

Mobile browser compatibility involves adjusting the website’s content to fit different screen sizes and resolutions. Images, for example, may need to be aligned differently on mobile browsers compared to desktop browsers. It is essential to ensure that your website offers a seamless experience across various mobile operating systems and screen sizes.

How to Perform Cross-Browser Testing

To perform browser testing effectively follow these steps

Start with your default browser: Begin by checking the web application or website on your default browser. Look out for any issues, such as problems with screen resolution, breakpoints, JavaScript behavior, or keyboard navigation. Keep in mind that some of these defects might be specific to browsers and fixing them might not completely resolve compatibility issues.

Choose browsers for testing: Analyse web traffic data to determine which browsers are most popular, among your site visitors. Based on this information select a range of browsers for testing the compatibility of your website.

Conduct browser testing: Test your website thoroughly using the selected range of browsers to identify any bugs or glitches that may arise across different platforms. Take note of the quantity and seriousness of the problems encountered. 

Classify the browsers that were tested into three categories: high risk, medium risk, and low risk. This classification should be based on the number and severity of issues encountered. It is important to prioritize fixing bugs in high-risk browsers to minimize the chances of those bugs appearing in low-risk browsers.
