Cypress Component Testing: Isolate UI Without Full E2E Setup

Mount React, Vue, or Svelte components in Cypress for fast feedback alongside Playwright E2E.

**Cypress** supports **component testing** in addition to end-to-end browser tests. Developers mount single components with props and stub dependencies, getting visual and behavioral feedback in the Cypress runner.

Configuration pairs with Vite or webpack dev servers depending on framework adapters documented on `docs.cypress.io`. Use for design-system primitives, form validation, and stateful widgets.

Component tests do not replace E2E coverage for routing, auth cookies, or cross-service flows. Combine with Playwright or Cypress E2E for critical journeys.

Pin Cypress major versions with framework plugins. Run component tests in CI parallel to unit tests for faster feedback than full browser suites.
