E2E tests are at the top of the test pyramid. E2E tests simulate real user flows and interactions, testing the system as a whole. These tests help ensure that all parts of the application work together as expected, from the user interface to the backend systems.

We’re going to use Cypress as the E2E test framework in this book. Cypress is a powerful tool for E2E testing of modern web applications. Its unique approach sets it apart from many other testing tools – instead of using Selenium, a common engine for many testing systems, Cypress operates directly on the actual browser, resulting in more reliable tests and a superior debugging experience.

You can either install Cypress into an existing project (like what we’re doing in this book) or install it in another folder other than your project. Cypress has been added as a project dependency in the code base in GitHub (provided in the Technical requirements...
