In their own words
Roborazzi
Roborazzi is an open-source library for screenshot testing in JVM-based Android integration tests. It records images, compares them with saved baselines and can fail verification when a screenshot differs. Through Robolectric, Android tests can run as JVM tests without a device or emulator. Capture options include Jetpack Compose nodes, Espresso views, Android Views and Compose lambdas; the library can also create screenshot tests for Compose previews and common Compose Multiplatform previews. It supports Compose Desktop and JVM preview tests, rendering images with the host’s Skia, while Compose Multiplatform iOS support is experimental. Gradle tasks cover recording, comparison and verification, and the project documents GitHub Actions workflows for screenshot checks in CI. An IDE plugin shows test screenshots in IntelliJ IDEA and Android Studio. Optional capabilities include UI-tree JSON output, accessibility checks, animated GIF or APNG capture, and experimental AI image assertions. Roborazzi is free, available on Maven Central and licensed under Apache License 2.0. It has no direct Bazel support, and graphics may render differently across operating systems.
