Cypress is an e2e testing tool that allows for testing web applications directly in the browser. It provides native access to the browser without using Selenium, making tasks like taking screenshots and recording videos possible. Some limitations are that it only supports single-page applications and one browser tab at a time. Cypress prioritizes developer experience through features like fast testing, intuitive debugging, and integration with continuous integration systems and dashboards. Many large companies have adopted Cypress for their e2e testing needs.

4. Agenda What is Cypress?
Why it is so good?

5. Cypress is all in one

6. Cypress does not use Selenium

7. Cypress has native access to everything
● Cypress is a Node.js server process
This makes performing tasks such as taking screenshots, recording
videos, general file system operations and network operations possible.
● Cypress tests run inside of the browser
You have real, native access to everything in your application under test.

8. Trade-offs
● Cypress is not a general purpose automation tool
● Cypress commands run inside of a browser
● There will never be support for multiple browser tabs
● You cannot use Cypress to drive two browsers at the same time
● Each test is bound to a single origin

9. A test runner built for humans

10. Cypress runs much, much faster

11. Debugging

12. CI + Dashboard

13. Who is using it?
