Unit tests allow you refactor your code with confidence and usually run blazingly fast! But how do you ensure that your UI looks as expected? Espresso tests are hard to set up, prone to flakiness and require APKs, emulators, dexing, ADB…ugh.

This talk will explore both the use cases for Paparazzi, as well as go under the hood discussing its interaction with LayoutLib, the driver behind Android Studio’s Layout Inspector feature. It’ll also introduce and/or discuss exciting new upcoming features.
