Expo Test Runner (Deprecated)

The `expo-test-runner` package (version 0.3.12 is given) is officially deprecated and its GitHub repository was archived on September 30, 2022. It was designed as a script to enhance the test experience within Expo projects, primarily serving as a wrapper or preset for Jest. While it previously facilitated testing in Expo environments, its functionality has since been integrated into, or superseded by, other tools within the main Expo monorepo. For current Expo application testing, the recommended approach is to use `jest-expo` in conjunction with `@testing-library/react-native`. `jest-expo` acts as a Jest preset that handles much of the necessary configuration and mocks for the Expo SDK, enabling unit and snapshot testing across various platforms, including iOS, Android, web, and Node. Developers should migrate from `expo-test-runner` to `jest-expo` for active development and support.
