Flaky React Native component tests usually stem from missing awaits in RNTL v14 async render or waitFor misuse. Apply version-aware guidance to fix async flows, ensure correct query priority, and match jest-expo presets to your React Native version.

React Native Testing Library v13 uses synchronous render, while v14 uses asynchronous render. This version difference dictates how you handle async flows, await missing errors, and manage query priority rules in Expo component test files.

Prefer userEvent over fireEvent for React Native component tests to simulate realistic user interactions. Following this best practice alongside accessible query rules like getByRole keeps your assertions clear and stable across releases.

To set up jest-expo presets for React Native testing, ensure the transforms match your React Native version. Determine whether your project uses RNTL v13 or v14 and configure the preset accordingly to enable accurate component test execution.

WaitFor misuse causes React Native testing failures by incorrectly timing async assertions and interactions. Avoiding this anti-pattern, along with applying recommended Jest matchers and version-specific async behavior rules, keeps your component tests stable across releases.

The best query priority rules for React Native Testing Library prioritize getByRole to keep assertions accessible and clear. Applying these rules, along with recommended Jest matchers, ensures your component test files remain stable and maintainable.
