Automating IS Regression Testing with SSIM Image Comparison and Async Rendering

This article describes how the Inspiration Spaces (IS) platform implements an automated regression testing pipeline that uses SSIM image similarity, asynchronous rendering, and pre‑defined sample rooms to dramatically reduce manual effort, improve detection of rendering bugs, and streamline cross‑team collaboration.

Page Difference Detection for Automated Regression Testing in Mobile Apps

The paper proposes a method for automated regression testing in mobile apps by detecting page differences via layout segmentation, ORB alignment of scrollable areas, SSIM similarity, and CNN filtering to ignore scroll or cursor changes while highlighting semantic UI changes, demonstrated on the Xianyu app.
