Maestro
Maestro is a mobile testing framework that replaces imperative test code with declarative YAML flows. You describe what the user does — tap this, type that, assert visible — and Maestro handles synchronization, retries, and cross-platform execution. This guide covers the flow syntax, handling dynamic content, CI integration, and how Maestro compares
Testing
Maestro takes a different approach to mobile UI testing than most frameworks. Instead of writing JavaScript or Python test code, you define flows in YAML. Instead of requiring build-time instrumentation, it works with any app — debug builds, release builds, or even apps you don't have the source for.
Testing
Running mobile E2E tests locally is one thing. Getting them to run reliably in CI is another problem entirely. You're dealing with emulators that need time to boot, builds that need to be cached, iOS simulators that require macOS runners, and Android emulators that need KVM acceleration or
Testing
End-to-end testing React Native apps is hard. You have two platforms, hardware variance, async bridge operations, and a runtime that doesn't behave like a browser. Detox was built specifically to solve this — it's a gray-box E2E framework that talks directly to your app's native
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
