ReDeCheck: An automatic layout failure checking tool for responsively designed web pages

Since people frequently access web sites with a wide variety of devices (e.g., mobile phones, laptops, and desktops), developers need frameworks and tools for creating layouts that are useful at many viewport widths. While responsive web design (RWD) principles and frameworks facilitate the development of such sites, there is a lack of tools supporting the detection of failures in their layout. Since the quality assurance process for responsively designed web sites is often manual, time-consuming, and error-prone, this paper presents ReDeCheck, an automated layout checking tool that alerts developers to both potential unintended regressions in responsive layout and common types of layout failure. In addition to summarizing ReDeCheck’s benefits, this paper explores two different usage scenarios for this tool that is publicly available on GitHub.
