Overview of this book

Cypress is a modern test automation framework for web-based frontend apps. Learning Cypress will help you overcome the shortcomings of conventional testing solutions such as dependency graph problems, the steep learning curve in setting up end-to-end testing packages, and difficulties in writing explicit time waits for your tests. In End-to-End Web Testing with Cypress, you’ll learn how to use different Cypress tools, including time travel, snapshots, errors, and console output, to write fail-safe and non-flaky tests. You’ll discover techniques for performing test-driven development (TDD) with Cypress and write cross-browser tests for your web applications. As you advance, you’ll implement tests for a sample application and work with a variety of tools and features within the Cypress ecosystem. Finally, this Cypress book will help you grasp advanced testing concepts such as visual testing and networking. By the end of this book, you’ll have the skills you need to be able to set up Cypress for any web app and understand how to use it to its full potential.

Understanding actionability

Now that we know what Cypress commands are, and where and when to use them, we need to understand the thought and operation process of Cypress when executing tests. In this section, we will cover how Cypress interacts with commands, how it ensures that elements are visible and actionable, and even how animation in elements is handled. We will also cover how Cypress determines actionability before any command is completed.

Actionability is the ability of Cypress to perform an action on a specific element in the Document Object Model (DOM). Cypress has commands whose sole intention is to interact with DOM elements. The commands act "as a user" and simulate interaction with the user interface of an application. Cypress events are responsible for the behavior of the commands as it sends the events to the browser, making it seem like user interaction on the application's user interface.

The following are some commands in Cypress that directly...
