v13 · now with component testing

Tests that watch
themselves run.

Write end-to-end tests in real JavaScript, watch every click and assertion replay in the browser, and know exactly why a test failed — not just that it did.

Every assertion, accounted for.

No flaky waits, no guessing why CI is red. Every command is logged, snapshotted, and replayable.

01

Time-travel debugging

Hover any command in the log to see a DOM snapshot from that exact moment in the test.

cy.get('.btn').click()
→ snapshot saved
02

Automatic waiting

No sleep(5000). Commands retry against your app's real state until they pass or time out.

cy.get('.toast')
.should('be.visible')
03

Network stubbing

Intercept, delay, or mock any request without touching your backend.

cy.intercept('GET', '/api/user',
{ fixture: 'user.json' })
04

Component testing

Mount a single React, Vue, or Svelte component and test it in isolation — same API, no e2e overhead.

mount(<Checkout />)
