Keeping your Pixels Perfect 📸: Paparazzi 1.0

Unit tests allow you refactor your code with confidence and -- if architected correctly -- 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. Snapshot tests get you closer but also rely on instrumentation tests.

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!
