    Cypress.io

    Fast, easy and reliable end-to-end testing for anything that runs in a browser. Cypress has been made specifically for developers and QA engineers, to help them get more done. Cypress benefits from our amazing open-source community - and our tools are evolving better and faster than if we worked on them alone. Cypress is based on a completely new architecture. No more Selenium. Lots more power. Cypress takes snapshots as your tests run. Simply hover over commands in the Command Log to see exactly what happened at each step. Stop guessing why your tests are failing. Debug directly from familiar tools like Chrome DevTools. Our readable errors and stack traces make debugging lightning fast. Cypress automatically reloads whenever you make changes to your tests. See commands execute in real-time in your app. Never add waits or sleeps to your tests. Cypress automatically waits for commands and assertions before moving on. No more async hell.
