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
