Chapter 7: End-to-End UI Testing with Cypress

In previous chapters, we learned how to test applications at the component level using React Testing Library. In this chapter, we will learn how to test applications at the system level by executing end-to-end testing using Cypress. End-to-end tests play an essential role in helping teams gain the confidence their applications will work as expected for end users in production. By including end-to-end tests in test strategies, teams can gain a lot of knowledge about how applications behave when all dependencies work together. Cypress is a modern, JavaScript end-to-end testing framework that can handle anything that runs in the browser, including applications built with popular frameworks such as React, Angular, and Vue. Cypress features allow teams to install, write, run, and debug tests within minutes.

In addition to system-level testing, it provides the ability to write unit and integration tests, making the framework great for developers...
