## What it is
jest-axe is a custom Jest matcher wrapping axe-core that lets you assert rendered HTML has no accessibility violations. It runs automated a11y checks in JSDOM and reports violations in Jest's familiar expect format.

## Use cases
- test that my React components have no accessibility violations
- add automated a11y checks to my Jest test suite
- assert rendered HTML passes axe-core accessibility rules
- catch missing alt text and ARIA issues in unit tests
- run accessibility linting as part of CI tests

## When to choose
- you already use Jest and want automated accessibility assertions
- you want axe-core violations reported as readable Jest failures
- you're testing React, Vue, or plain HTML output in JSDOM

## When to avoid
- you need color contrast checks, which don't work in JSDOM
- you expect automated testing to guarantee full accessibility - manual and assistive-tech testing is still required
- you use a test runner other than Jest without matcher support
