Compatibility testing is a type of non-functional testing that helps in checking the web or mobile applications on various computing platforms being used by end-users. It validates that an application works as expected when accessed through different browser-OS combinations (i.e. on popular browsers like Firefox, Chrome, Edge, Safari—on any of the popular operating systems like Windows, macOS, iOS, and Android).

Different devices (i.e. users can view and interact with the application on popular devices, smartphones, tablets, desktops, and laptops, etc.).

Therefore, the objective of compatibility testing is to release web or mobile applications that deliver a uniform user experience on a diverse, ever-growing range of browsers, operating systems, and devices.

Compatibility testing is a very wide topic and it would be a long article to cover it all here. That is why we would like to focus on the compatibility testing for websites and web applications for the rest of this article.

Why is Cross-Browser Testing Important?

If a website or web application works well on one browser, that doesn’t imply that it will work well on the other browsers too. Thus, this testing helps you to ensure that it runs on different browsers without any errors.

To identify what breaks on which browser and to fix the website accordingly we need to perform this testing. If a browser is not at all supported, then the users can easily be informed about it to manage their expectations from the outset.

What is the impact of ignoring Cross-Browser Testing?

Imagine that a user is trying to access a website on a specific browser but the page does not display correctly. The user is likely going to do one of two things. First to assume that the site has an issue and leave to return later or second assume that the site is broken and leave to find an alternative.

Browser vendors follow Open Web Standards, but they have their own interpretations of it. Since they each render HTML, CSS, and JavaScript in unique ways, thoroughly debugging the website’s source code is not enough to ensure that your website will look and behave as intended on different browsers (or different versions).

Cross-browser testing helps with that by pinpointing browser-specific compatibility errors so developers can debug them quickly. It helps ensure that all target audiences can access the website without issues.

How Do I Select Browsers for Testing?

The combination number of browsers, devices, and operating systems out there makes it impossible to build for and test every combination that may exist. Hence, we at Quality Professionals leverage market-leading tools to automate the test where it gets done once and replicated on all needed combinations.

However, for manual compatibility testing, it would be more realistic to focus the effort on maximizing the web application reach within the organization’s target market. To do this, we first work with our clients to lock down the most critical browsers and versions

Based on market share (popularity) in a specific country or region(s).
Based on the traffic stats of the web application itself. We usually work with the business or marketing team that handles the application or website.

Our test engineers take these stats and accordingly prioritize the effort based on starting with common ones first. We also test responsive to ensure we mimic users accessing from smart devices.
