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.

Chapter 8: Understanding Variables and Aliases in Cypress

Before we get started on how variables and aliases work in Cypress, it is important to understand what we covered in the previous chapters on how to write tests in Cypress, how to configure tests, and even how to use Cypress to write applications in the proper way by following a test-driven development approach. The background information provided in the previous chapters of this book will give you a good grounding as we dive into how variables and aliases work. By exploring what variables and aliases are, we will understand how we can create references in Cypress, which will ease our test writing process and the complexity of our tests. Understanding how to use variables and aliases will not only make you write better tests but also write tests that are easy to read and maintain.

In this chapter, we will focus on writing asynchronous commands to make use of the variables and aliases that Cypress comes bundled with. We will...
