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. Come find out how we're improving the UI testing loop on Cash App with Paparazzi -- an Android testing library to render your application screens without a physical device or emulator! This talk will explore both the use cases for Paparazzi, as well 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.
