Cypress is a test automation tool designed for web applications. It allows you to write and execute end-to-end tests that replay user interactions within the browser. With Cypress, you can test your web application's functionality.

Cypress has a unique architecture that runs directly in the browser. It has features like real-time reloading, automatic waiting, and time-travel debugging, which make test creation and debugging more efficient. Using Cypress, you can automate tasks such as handling asynchronous operations, interacting with elements, and making assertions. It provides an intuitive and powerful API that simplifies test script development.
