Description

As a method for detecting layout defects in web pages, image-based visual regression testing is proposed. It makes it easier to spot differences in layout by displaying web pages before and after any changes side by side and highlighting the differences in layout. However, it has the problem that it takes time to find unintended differences in layout that are not based on HTML code. Therefore, this paper implements MixVRT which is a visual regression testing tool that highlights layout defects in web pages. It detects differences by comparing images and detects changes due to HTML codes changes on the web pages before and after changes and compares them to detect layout defects. From evaluation experiments, the time find to layout defects can be reduced.
