Visual Test-Driven Development For Responsive Interface Design

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.
