About Cypress
Cypress provides end-to-end, integration, and unit testing for web applications with real-time reloading, time travel debugging, and automatic waiting.
Key Features
- In-browser testing
- Time-travel debugging
- Automatic waiting
- Network stubbing
- Real-time reloading
- Visual Test Runner
Cypress redefined frontend testing by running tests directly in the browser rather than through a remote protocol. This architecture gives tests direct access to the DOM, network layer, and application state, making them faster and more reliable than Selenium-based alternatives. The Test Runner provides a visual interface showing your application and tests side by side, with time-travel debugging that lets you step through each command. Cypress excels at testing single-page applications and complex user interactions, though its limitation to Chromium-based browsers and Firefox (no Safari/WebKit) has driven some teams to Playwright.
