Cypress Tutorial

Cypress is a renowned Javascript-based open-source, easy-to-use end-to-end testing framework primarily used for testing web applications. Cypress is a relatively new player in the automation testing space and has been gaining much traction lately, as evidenced by the number of Forks (2.7K) and Stars (42.1K) for the project. LambdaTest’s Cypress Tutorial covers step-by-step guides that will help you learn from the basics till you run automation tests on LambdaTest.

Chapters:

What is Cypress? -
Why Cypress? - Learn why Cypress might be a good choice for testing your web applications.
Features of Cypress Testing - Learn about features that make Cypress a powerful and flexible tool for testing web applications.
Cypress Drawbacks - Although Cypress has many strengths, it has a few limitations that you should be aware of.
Cypress Architecture - Learn more about Cypress architecture and how it is designed to be run directly in the browser, i.e., it does not have any additional servers.
Browsers Supported by Cypress - Cypress is built on top of the Electron browser, supporting all modern web browsers. Learn browsers that support Cypress.
Selenium vs Cypress: A Detailed Comparison - Compare and explore some key differences in terms of their design and features.
Cypress Learning: Best Practices - Take a deep dive into some of the best practices you should use to avoid anti-patterns in your automation tests.
How To Run Cypress Tests on LambdaTest? - Set up a LambdaTest account, and now you are all set to learn how to run Cypress tests.
