We use ad-blockers as well, you know. We gotta keep those servers running though. Did you know that we publish useful books and run friendly conferences — crafted for pros like yourself? E.g. our upcoming SmashingConf London, dedicated to all things web performance.
When designing a graphical user interface, there is always an open question: How do we automate testing for it? And how do we make sure the website layout stays responsive and displays correctly on all kinds of devices with various resolutions? Add to this the complications arising from dynamic content, requirements for internationalization and localization, and it becomes a real challenge.
In this article, I will guide you through an interesting new layout testing technique. Using Galen Framework, I will provide a detailed tutorial for writing meaningful generalized layout tests, which can be executed in any browser and on any device and at the same time used as a single source of truth in your design documentation.
Testing responsive websites is a laborious task. Until now, implementing a stable and maintainable automated solution for cross-browser and cross-device testing of a responsive layout has been nearly impossible. But what if we had an opportunity to write visual tests for responsive websites? What if we could describe the look and feel of an application and put this directly into our tests?
Upon considering this question, I decided to also look at another interesting side of visual testing. For quite a long time I have been a fan of the test-driven development (TDD) methodology. It helps me in my daily programming work. TDD enables me to formalize the task and to make sure everything is implemented according to the requirements.
