## What it is
React Testing Library is a lightweight set of utilities for testing React components by rendering them into a DOM and querying them the way a user would. It encourages tests that avoid implementation details, making test suites resilient to refactoring.

## Use cases
- test react components
- write maintainable ui tests that survive refactors
- query dom elements by label or role like a user would
- simulate user interactions in component tests
- migrate from enzyme to a modern testing approach
- test react hooks with renderHook
- improve accessibility by testing with semantic queries

## When to choose
- you write React component tests with Jest, Vitest, or another test runner
- you want user-centric tests that don't depend on component internals
- you want to encourage accessible markup via role- and label-based queries

## When to avoid
- you need end-to-end tests in a real browser (use Playwright or Cypress)
- you need to assert on component state, props, or lifecycle methods directly
- you are testing non-React frameworks (use the framework-specific Testing Library wrapper)
