React Native app testing
React Native app testing across iOS and Android
One codebase should not mean two test suites. Klarent authors one test in plain English and runs it on both platforms, including the WebView screens in between.
The React Native testing problem
Why React Native tests break
One codebase, two runtimes
The same flow can render differently per platform, even from a single codebase.
Native and WebView in the same flow
Tests jump between native screens and WebView content mid-flow.
testID dependency
Detox and Appium suites depend on testID attributes that the app team has to add and maintain.
Upgrades shift the element tree
Every React Native or dependency upgrade can shift the element tree under existing tests.
Native module boundaries
Native modules can behave differently across iOS and Android, creating platform-specific automation gaps.
Async and animation timing
Animations, asynchronous rendering and state updates can make tests flaky and timing-sensitive.
Platform
Everything your mobile QA team needs
From generating your first test to keeping it green after every app update. Klarent handles every step.

Platform capabilities
Built for how React Native app testing actually works
One test, both platforms
No separate iOS and Android suites to keep in sync.
Works without testID attributes
Elements are identified by intent, not by hard-coded selectors.
Automatic native / WebView handling
Native and WebView context switches are handled automatically inside a single flow.
Self-healing locators
Locators adapt automatically through React Native and dependency upgrades.
Per-platform assertions
Assert per platform for the moments where iOS and Android genuinely diverge.
Test coverage
What you can test in a React Native app
Navigation and tab flows
Navigation stacks and tab flows, including React Navigation patterns.
Native modules and bridge behavior
Camera, storage, biometrics and permission requests across the native bridge.
Embedded web views
WebView-hosted screens and embedded checkout flows.
Notifications and deep links
Push notifications and deep links on both platforms.
Platform-specific UI divergence
The same journey validated where iOS and Android genuinely diverge.
Network and offline states
Offline mode, slow connections, network interruptions and recovery flows.

Klarent vs. traditional QA
Klarent vs Detox, Appium and Maestro
| Detox / Appium / Maestro | In-house framework | Klarent | |
|---|---|---|---|
| Authoring language | JavaScript/TypeScript (Detox) or driver-specific scripts (Appium, Maestro) | Custom framework code, owned internally | Describe the flow in plain English. No code |
| testID dependency | Requires testID or accessibility label props added by developers | Depends on the same testID conventions | Elements identified by intent - no testID props required |
| Cross-platform reuse | Separate suites or config per platform | Shared framework, but still two suites to maintain | One test runs on iOS and Android together |
| Maintenance load | Every React Native upgrade breaks selectors. Scripts need manual fixes | Framework absorbs some churn, but still needs dedicated engineers | Self-healing locators adapt automatically |

FAQs
Upload your iOS and Android builds (or connect your CI pipeline), describe the journey once in plain English, and Klarent runs the same test on both platforms - including any WebView screens in the flow - and reports results per platform.
No. Klarent identifies elements by intent, not by hard-coded testID or accessibility-label props, so there is nothing extra for your developers to add or maintain.
Yes. Klarent authors one test from a single description and executes it on both platforms, with per-platform assertions available for the moments where iOS and Android genuinely diverge.
Both. Klarent supports bare React Native and Expo apps, including development and release builds, whether you build with EAS or your existing CI/CD pipeline.
Klarent detects and switches between native and WebView context automatically inside a single flow, so a test can move from a native screen into an embedded checkout or web content without extra setup.
Detox requires JavaScript/TypeScript test code and testID attributes that your developers maintain. Klarent tests are described in plain English, identify elements by intent, and self-heal automatically through React Native and dependency upgrades.
Klarent's self-healing locators detect the changes an upgrade introduces to the element tree and adapt the test automatically, so it keeps passing without manual rework.
Yes. Klarent tests native module and bridge behavior, including camera, storage, biometrics and permission prompts, alongside standard React Native UI flows.
