1React Native Testingreact-native-testing is an agent skill for writing React Native Testing Library tests on v13 with React 18 sync render APIs and v14 with React 19 plus async render. It instructs agents to detect the installed @testing-library/react-native version from package.json and load the matching api-reference file because training data may be outdated on sync versus async behavior. Query priority runs getByRole first, then label, placeholder, text, display value, and testID as last resort, with clear rules for get, query, and find variants including findBy for async elements instead of waitFor plus getBy. Interactions prefer async userEvent setup for press, longPress, type, clear, paste, and scrollTo, reserving fireEvent for unsupported cases per the version-specific reference. Jest matchers such as toBeOnTheScreen, toBeVisible, toBeEnabled, toHaveTextContent, and toHaveAccessibleName ship automatically with RNTL imports. Rules ban side effects inside waitFor, multiple assertions per waitFor, manual cleanup or act wrapping, and legacy accessibility props when ARIA equivalents exist. Developers reach for it when authoring, reviewing, or fixing React Native component test files that import @t.3.2kinstalls
