Overview of this book

Single page applications (SPAs) have become the standard for most web experiences. Angular, with its batteries-included approach, has emerged as a powerful framework for simplifying the development of these interfaces by offering a comprehensive toolbox. This book guides you through the Angular ecosystem, uncovering invaluable design patterns and harnessing its essential features. The book begins by laying a strong foundation, helping you understand when and why Angular should be your web development framework of choice. The next set of chapters will help you gain expertise in component design and architecting efficient, flexible, and high-performing communication patterns between components. You’ll then delve into Angular's advanced features to create forms in a productive and secure way with robust data model typing. You'll also learn how to enhance productivity using interceptors to reuse code for common functionalities, such as token management, across various apps. The book also covers micro frontend architecture in depth to effectively apply this architectural approach and concludes by helping you master the art of crafting tests and handling errors effortlessly. By the end of this book, you'll have unlocked the full potential of the Angular framework.

E2E tests with Cypress

E2E tests aim to evaluate the system from the user’s point of view, simulating operations such as typing in a field, clicking on a button, carrying out the assertion, and evaluating the messages on the screen, just as a user would evaluate whether the action was successful or not.

In the Angular ecosystem, in the past, there was a tool called Protractor to help with this type of testing, but it was discontinued by the Angular team in favor of other, more focused open source tools.

Among these new tools, we are going to use one of the most popular ones, called Cypress.

The Cypress framework is a tool that aims to help developers create and run all types of tests in the test pyramid, from unitary to E2E.

Let’s see it in action in our project. For that, we need to install and configure it. Follow these steps to install and configure Cypress:

  1. We will use the Angular CLI to install and configure Cypress. In the command line of your...
