The importance of UI regression testing

As the final stage of website development, UI regression testing plays a vital role in the process of creating high-quality software.

There is an opinion that user interface testing is a simple and low-priority task that has nothing to do with product quality and success. But when we look at the issue in more detail, it turns out that a quality UI is a fairly large part of the project’s success. And this is testers and managers who are faced with a number of problems, such as the unreadiness of QA specialists for this type of work, the absence of UI documentation, design mismatch, and the need to interact on UI issues with programmers and designers.

To avoid all the above issues, it is critically important to employ an effective tool enabling you to find visual regressions on your website faster. If you are aiming to get that solution, we recommend you to check the diffy.website that offers users extensive functionality for UI regression testing.

Why Website Testing Is so Important?

After completing the basic work of creating the software part of a web resource, a QA specialist receives all the necessary documentation and materials and proceeds to website testing. To organize the process in the best way, it is critically important to plan all its steps and assessment criteria in advance. Only, in this case, you will not miss out any detail and do the testing pixelwise.

What Is Important in UI Testing?

When checking the page layout/ design, the tester checks the location of all the elements, the consistency of their positions with the provided mock-ups, and the optimization of both images and graphics. At the further stage, the validity of the code is tested. In the process of typesetting, it is important to review the correct hierarchy of objects and ensure its validity upon work completion.

Having completed the validation check, the QA specialist proceeds to the cross-browser compatibility check. In other words, he checks the website performance in various browsers with different screen settings. As you can see, UI testing is a very time-consuming process, which requires real professionalism and a lot of efforts from the QA.

Testing the Cross-Browser Compatibility

Why should you test the website for cross-browser compatibility? Today, there are a number of popular web browsers, such as Google Chrome, Safari, Mozilla Firefox, Internet Explorer, and Opera. Each of them adheres to the general recommendations of rendering page markup, but at the same time, each processes the code in accordance with the features of its own engine.

Complicated by the fact that new versions of browsers appear quite often, the page that looks great, for example, in IE9, will not necessarily look the same in IE7 or IE8. Therefore, the process should take into account the list of widely used browsers. The stage of website cross-browser compatibility testing is also quite long, but the result is worth it.

Final Verdict

As the final stage of website development, UI regression testing plays a vital role in the process of creating high-quality software. The more complex the site is, the longer it takes to check and debug it. Unfortunately, there are many examples where developers and customers miss out the website testing phase, which almost always leads to greater financial and time costs as well as poor user experience.
