React Native SDK for Nami - No-code paywall and onboarding flows with A/B testing.

// Mock react-native BEFORE importing the SDK — `../Nami` resolves
// the native module via TurboModuleRegistry at import time.
const reset = jest.fn().mockResolvedValue(undefined);
// The wrapper reads `result?.success` (see Nami.ts), so the mock must
// return that shape — not a plain boolean.
const configure = jest.fn().mockResolvedValue({ success: true });
const sdkConfigured = jest.fn().mockResolvedValue(false);
const sdkVersion = jest.fn().mockResolvedValue('test');
