Runs in the browser: Cypress executes tests inside the browser, giving real-time control over application behavior. Automatic waiting: No need for manual wait—Cypress waits for elements to appear and actions to complete. Time travel: Cypress shows a visual step-by-step history of your test in the UI test runner. Real-time reloads: Tests re-run automatically as you save them. Powerful debugging: With built-in developer tools and readable errors.
