Snapshot testing (and more!) with Paparazzi

on YouTube ↗35m

" summary

Paparazzi renders Android UIs on the JVM so snapshots run in seconds instead of the usual 2–4 minute build+deploy loop; Cash App uses it in production and Google, Twitter and Dropbox adopt it. It drives LayoutLib plus a JNI-backed Skia pipeline, supports Compose (since 1.0), a Gradle plugin that prepares merged resources, and platform-specific native libs for four OS/arch targets. Known limits: layoutlib bugs become test bugs, app-module merged resources are still unsupported.
