A Jest matcher that performs image comparisons using pixelmatch, behaving like Jest snapshots. It is most commonly used for visual regression testing of browser-rendered UIs.

Use cases

• catch visual regressions in UI tests
• compare screenshots against a baseline in Jest
• snapshot test rendered web pages
• diff images in automated browser tests
• update image snapshots when UI changes are intentional
• add pixel diff threshold and blur to reduce flaky visual tests

When to choose

• you already use Jest and want image snapshot assertions
• you run browser tests (e.g. Puppeteer/Playwright) and need visual regression checks
• you want configurable diff thresholds, blur, and snapshot update workflows

When to avoid

• you don't use Jest as your test runner
• you need standalone image comparison outside a test suite
• you need cross-browser visual testing infrastructure rather than a matcher
