Lights, Camera, Snapshot! What’s New in Paparazzi 2.0
summary
Paparazzi 2.0 breaks the JUnit 4 rule into a separate SDK that loads Android Studio’s layoutlib, exposes setup/teardown lifecycle hooks, and returns an abstract snapshot/clip instead of raw BufferedImages so other engines (Robolectric, headless iOS) can plug in. Image diffing moves from pixel-perfect and “off-by-two” hacks to perceptual metrics — MS‑SSIM shows promise with a 98% threshold on examples — while FLIP, SIFT and ΔE2000 are being evaluated. Gradle plugin no longer forces AGP/Kotlin versions, adds API36, embeds failure diffs in reports, introduces a root-level snapshot browser and experiments with a keyframes API for clips and fake system UI.
