React Native Testing Library

Deep API reference for @testing-library/react-native v13 and v14.

Scope: unit + component tests with Jest + RNTL. For end-to-end UI flows on real devices/simulators, use Maestro — declarative YAML flows, no code, runs against the built app. RNTL and Maestro are complementary, not alternatives.

IMPORTANT: API signatures, sync/async behavior, and available functions differ between v13 and v14. Always check the project's package.json and load the matching version reference rather than relying on memorized patterns.

Version Detection

Check @testing-library/react-native in package.json:

• v14.x → load reference-v14-api (React 19+, async APIs, test-renderer)
• v13.x → load reference-v13-api (React 18+, sync APIs, react-test-renderer)
