1React Native Testingreact-native-testing is a Callstack agent skill that encodes React Native Testing Library anti-patterns so solo and indie builders stop shipping flaky or misleading mobile tests. It walks through twelve recurring mistakes—wrong query variants, skipping *ByRole, weak assertions, misused waitFor, redundant act(), fireEvent instead of userEvent, destructuring render, UNSAFE_root, manual cleanup, legacy accessibility props, missing awaits on v14 async APIs, and reliance on removed APIs—with BAD/GOOD snippets you can paste into reviews or refactors. The skill fits builders using Claude Code, Cursor, or Codex on Expo or bare React Native apps who want CI that fails for real regressions, not query throws or timing races. Use it while authoring or reviewing component tests, before tightening a Ship-phase test suite, or when upgrading to RNTL v14. It is editorial guidance, not a test runner: you still need Jest and @testing-library/react-native installed in the repo.2.4kinstalls
