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
Mobile Testing
Capacitor native plugins are the points in your application where web code makes requests to native capabilities — camera hardware, the device filesystem, push notification infrastructure. In unit and integration tests, none of those native capabilities exist. The test runner is Node.js; there is no camera, no iOS sandbox, no
Mobile Testing
Capacitor bridges the gap between web and native mobile, but that bridge creates a testing challenge. Your business logic calls Camera.getPhoto() or Geolocation.getCurrentPosition(), but in a Jest environment there is no native runtime — those calls throw immediately. Meanwhile, your Cypress tests run in a browser where the Capacitor
Mobile Testing
End-to-end testing a Capacitor application is fundamentally different from testing a pure native app. Your app is a native shell containing a WebView. User interactions flow from native gesture recognizers into the WebView's JavaScript runtime and back out through the Capacitor plugin bridge. Both Detox and Appium can
Mobile Testing
Testing Ionic Angular applications requires navigating a collision between two opinionated frameworks, each with their own component lifecycle and dependency injection patterns. Angular's TestBed assumes synchronous or promise-based initialization; Ionic's components wrap Web Components and initialize asynchronously. Modal controllers, alert controllers, and navigation all introduce services
Mobile Testing
A Capacitor app CI/CD pipeline has more moving pieces than a typical web application. The web layer needs a standard JavaScript build, but then Capacitor must sync that output to native iOS and Android projects, each of which needs its own build toolchain, signing configuration, and deployment target. Add

Compose Multiplatform extends Jetpack Compose beyond Android, bringing the same declarative UI model to iOS, desktop (macOS, Windows, Linux), and web. But testing a UI that runs on four platforms is a different challenge than testing a single-platform app. This guide covers how to write and run Compose Multiplatform UI
Testing
Kotlin Multiplatform (KMP) lets you write business logic once and share it across Android, iOS, desktop, and web. But sharing code means shared bugs — and shared testing responsibilities. This guide covers everything you need to test KMP projects effectively. Why Testing KMP Is Different In a typical Android project, your

Kotlin Multiplatform's promise is compelling: write business logic once, run it on iOS and Android. But "write once" doesn't automatically mean "test once." Shared code can behave differently across platforms due to threading models, memory management, and standard library differences. This guide
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
Game Testing
Mobile games face a testing challenge that PC and console games don't: thousands of different devices, CPU/GPU combinations, OS versions, and screen sizes. A game that runs at 60fps on a Pixel 8 might choke on a mid-range Samsung from two years ago. A UI that'
