Mastering Screenshot Testing for Android Apps
summary
Compares Roborazzi and Google’s Compose Preview Screenshot Testing (CPST), showing a real setup that uses Roborazzi + Showcase with a screenshot-grad plugin, GitHub Actions automation and about 500 reference images; CI runs take ~10 minutes (local 1–2 minutes). Roborazzi offers fine-grained device/font/animation control and can export GIF sequences; CPST is faster and preview-driven but still experimental—fails on some device annotations and requires a separate source set. Tests produce three-image diffs (reference/actual/diff).
