User-generated content that alters the layout can complicate visual testing in dynamic scenarios due to its unpredictable nature. Visual testing aims to ensure that graphical interfaces appear correctly and consistently across various environments and input scenarios. When users can modify content—such as posting images, comments, or information—this can dynamically change how elements are presented on the webpage.

For instance, a user-generated video or an image may shift elements around, introducing variations in layouts that were not accounted for during initial testing. This variability makes it challenging to establish a single, reliable baseline for visual comparisons since the application’s appearance may change significantly based on content created by users.

In contrast, static images and pre-defined UI elements that do not change are less likely to create complications in visual testing because they conform to a consistent design, making visual verification straightforward. Fixed web application designs also maintain the same structure, thus eliminating variability that dynamic content introduces. This stability allows for clear comparisons against baseline expectations.
