## Summary Testing in React Native is essential to uncover mistakes and ensure code reliability as your app grows. Writing tests before code helps maintain testability, and structuring tests with Jest ensures independence and efficiency. Different types of tests, such as unit, integration, and component tests, play a crucial role in verifying app functionality and user interactions. ## Highlights To make your app more testable, start by separating the view part of your app—your React components—from your business logic and app state (regardless of whether you use Redux, MobX or other solutions). This way, you can keep your business logic testing—which shouldn’t rely on your React components—independent of the components themselves, whose job is primarily rendering your app’s UI!
