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:

Core References

TopicDescriptionReference
Core patternsQuery priority, render/screen, userEvent vs fireEvent, waitFor, 11 core rulescore-patterns
v13 API (React 18)Sync render, full method tables, fireEvent sync, React 19 compat shimsreference-v13-api
v14 API (React 19)Async render, await-based APIs, removed APIs, v13→v14 migration codemodsreference-v14-api
Anti-patternsWrong queries, waitFor misuse, unnecessary act, destructuring, missing awaitbest-practices-anti-patterns

Key Recommendations

  • Always use screen for queries — never destructure from render()
  • getByRole first with { name: '...' } option (most accessibility-aware)
  • findBy* for async elements — not waitFor + getBy*
  • userEvent over fireEvent — more realistic interaction simulation
  • queryBy* only for non-existence assertions (.not.toBeOnTheScreen())
  • v14: always await every API (including render, fireEvent, act)
