# RNTL Test Writing Guide

Component tests that use the queries and matchers as intended

## What this does

## About RNTL Test Writing Guide

This is guidance for writing tests with React Native Testing Library, covering render, screen, the query families (getBy, getAllBy, queryBy, findBy), Jest matchers, userEvent, fireEvent, waitFor, and async patterns.

It supports both v13, with React 18 and synchronous render, and v14, with React 19 and above and asynchronous render.

Use it when writing, reviewing or fixing React Native component tests - it applies to test files for components, to files importing RNTL, and when the conversation turns to writing component tests.
