Testing
End-to-end testing for React Native apps has historically been painful. Tests were slow, brittle, and tied to specific device states that were hard to reproduce. Detox was built specifically to address these problems with a gray-box testing approach that gives your test runner insight into the app&
Testing
If you're building a React Native app and need E2E tests, you'll eventually choose between Detox and Maestro. They're the two most widely used options, they take fundamentally different architectural approaches, and the right choice depends heavily on your team's structure and
Testing
React Native's cross-platform model means accessibility bugs can appear on iOS, Android, or both, often in different forms. A layered testing approach — jest-native for component tests, react-native-axe-core for runtime audits, and Detox for end-to-end screen reader behavior — catches issues at every
Testing
Choosing a cross-platform mobile framework is partly a testing decision. The tools, ecosystems, and philosophies around testing differ significantly between Kotlin Multiplatform, React Native, and Flutter. This comparison helps you understand the tradeoffs before you commit. The Core Testing Philosophy Difference KMP shares business logic but keeps native UI.
Testing
Running Detox tests locally is one thing. Getting them running reliably in CI is another. Mobile E2E tests have historically been the most painful part of CI/CD pipelines: emulators crash, builds are slow, and tests that pass locally fail for reasons that are hard to diagnose. This guide covers
Testing
Unit tests are the foundation of a React Native test strategy. They run fast, give immediate feedback, and catch logic errors long before they reach a device or simulator. Yet many React Native teams skip them or write tests that test nothing meaningful. This guide covers the practical patterns you
Testing
Native modules are the bridge between your JavaScript code and platform APIs — camera, geolocation, biometrics, push notifications, Bluetooth. They're essential for real apps, but they're also the reason React Native unit tests break: native modules don't exist in a Jest environment running on Node.
Testing
When it comes to end-to-end testing for React Native apps, two frameworks dominate the conversation: Detox and Appium. Both can drive real devices and simulators. Both support iOS and Android. But they take fundamentally different approaches, and that difference matters enormously for React Native projects specifically. This article
