A Method to Mask Dynamic Content Areas Based on Positional Relationship of Screen Elements for Visual Regression Testing

There are areas on an application screen where the content changes every time the screen is displayed such as advertisements and news articles (hereafter, dynamic content areas). When there are dynamic content areas, many differences in false positive are detected in Visual Regression Testing. Such differences due to dynamic content areas prevent the tester from efficiently checking the important differences. Therefore, specifying a dynamic content area as a masked area and excluding it from the comparison area is effective for reducing the human effort required to confirm these differences. We propose a method of accurately specifying the area to be masked based on the relative positional relationship of multiple screen elements and excluding dynamic content areas from the comparison area.
