React Native Harness

Bridge the testing gap: Jest-style tests in real native environments. Get the convenience of describe/it with full access to native modules.

Jest-Style Syntax, Native Power

Write familiar describe/it tests that run in real iOS and Android environments with full native module access.

Best of Both Worlds

Unlike Jest (Node.js only) or Maestro (UI-based), get convenient test syntax AND native environment execution.

Real Device & Simulator Testing

Execute tests directly on iOS simulators and Android emulators - catch platform-specific issues Jest can't see.

Native Module Testing

Test native modules, platform APIs, and device-specific functionality that's impossible with JavaScript-only runners.

Familiar Test Structure

Use beforeEach, afterEach, describe, it, expect - all the testing patterns you know and love from Jest.

Zero Configuration Setup

Drop-in replacement for your existing test workflow with TypeScript support and seamless CI/CD integration.
