Summary
If you're writing React Native tests and haven't touched RNTL in a while, your mental model is probably wrong. This skill covers both v13 and v14 APIs, which differ significantly in sync versus async behavior, especially around render and fireEvent. It auto-detects your project version from package.json and loads the right reference. The guide is opinionated in a good way: it pushes you toward userEvent over fireEvent, getByRole over getByTestId, and findBy over waitFor plus getBy. It also calls out the anti-patterns that trip people up, like putting side effects inside waitFor or manually calling act. Treat this as your source of truth when Claude's training data conflicts with current RNTL conventions.
