React Native Testing

This one helps you write and fix React Native component tests using Testing Library v13 and v14. It auto-detects your version from package.json and loads the right reference, which matters because v14 made render async and changed how fireEvent works. You get query priority rules (getByRole first, getByTestId last), the full userEvent API for interactions, and all the Jest matchers like toBeOnTheScreen and toBeVisible. The anti-patterns guide is honest about common mistakes like wrapping everything in act() or putting side effects in waitFor. Useful if you're tired of guessing which RNTL patterns are actually current.
