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.

Forcing actionability

Having understood what actionability is, and the checks that are required by Cypress to determine whether an element is actionable or not, it is also important to know how we can override mechanisms set in place by Cypress to check for actionability. In this section, we will focus on performing actions and commands even when the elements do not pass the actionability checks that Cypress enforces for the actionable commands. We will also learn how to safely implement override mechanisms for some elements and tests.

Overriding Cypress actionability checks

Actionability is very useful in Cypress tests as it helps us to find situations where users may not be able to interact with our application elements. At times, though, the actionability checks can get in the way of proper testing, which leads us to our next mission: overriding the safety checks.

In some tests, "acting like a user" may not be worth it as, at the end of the day, the goal is to...
