Jest Preset for Expo & React Native

jest-expo is a Jest preset designed to streamline the testing process for applications built with Expo and React Native. It handles most of the complex Jest configurations, including mocking native modules from the Expo SDK and React Native environments, enabling developers to focus on writing tests. The current stable version is 55.0.16, aligning with Expo SDK 55. The package follows Expo's release cadence, with major versions tied to SDK releases (typically every few months) and frequent patch updates. Key differentiators include its 'universal' testing capabilities, allowing tests to run and create multi-platform snapshots across iOS, Android, web, and Node.js environments, significantly simplifying cross-platform testing workflows.
