on GitHub

14.0.0-beta.0 (2026-01-20)

What's new

React 19 and React Native 0.78+

• Drops support for React 18.
• Requires React 19.0.0+ and React Native 0.78+.

Async APIs

The main APIs are now async to support React 19's async rendering (Suspense, use()):

• render, renderHook, fireEvent, and act return Promises and must be awaited.
• This flushes pending React updates before your assertions run.

New renderer

• Replaced deprecated react-test-renderer with Test Renderer.
• Improved DX (HostElement replaces ReactTestInstance).

container API

• screen.container is now safe to use.
• Returns a pseudo-element container wrapping the rendered elements.

Breaking changes

• Removed APIs: update (use rerender), getQueriesForElement (use within), UNSAFE_root (use container), and concurrentRoot option.
• Removed legacy queries: UNSAFE_getAllByType, UNSAFE_getByType, UNSAFE_getAllByProps, and UNSAFE_getByProps. Use standard queries like getByRole.
• Strict text validation: Text strings must be rendered within a <Text> component. The unstable_validateStringsRenderedWithinText option has been removed; validation is always on.
