About

This visual regression testing for React Native library enables developers to introduce visual regression tests to their apps for iOS and Android. Being heavily inspired by Detox, an end-to-end testing and automation framework, this library uses a similar API that makes setting up react-native-owl and running the tests locally and on your preferred CI service, seamless.

Learn more about the background behind this library in the announcement on the Formidable Blog.
