It is probably safe to assume that any developers reading this article are already testing their applications. At the bare minimum, you’re testing the feature you’re working on as you develop it and checking that it works with any existing code. Many of you are probably using some form of automated functional testing as well. These types of testing are certainly important and they help to ensure that your applications work as expected, but adding visual testing into the mix will improve your testing significantly.
Today, users access applications in a variety of ways, including wearables, smartphones, tablets, laptops, desktop PCs, and an increasing range of smart devices. Now, developers need to account for the ways in which these new and diverse technologies change how their software is presented to and perceived by their users. The typical forms of testing we’ve relied upon for so long simply can’t detect the problems that may exist on every possible device. This is why developers now need to test the visual aspects of their applications. In recent years, developers have started using visual testing methods, tools, and frameworks to meet these new challenges.
In this post, we make the case that it’s wise to use visual testing. Even if you, your team, or your organization are old hands at automated functional testing, we’ll explain why you should add visual testing into your existing infrastructure. We also offer advice about available tools, frameworks, and solutions that will help you get started. Whether you’re a novice developer or a seasoned veteran, the information presented in this post will help you deliver the best experience for your users.
