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 12: Visual Testing in Cypress

Before we get started with visual testing, you should have an idea of the other forms of testing and how we can use Cypress to accomplish this. The previous chapters of this book covered, at a basic to intermediate level, how to easily get started with Cypress, how to configure Cypress, and how you can optimize your use of Cypress to develop a more creative workflow for your test writing process. The background information in the previous chapters will provide you with the context required to tackle this chapter. Our focus in this last chapter of this book will be on visual testing using Cypress.

In this chapter, we will cover the basics of visual testing and understand why we need it. We will also learn about some of the tools we can use to carry out visual testing. The topics in this chapter will help you, as an engineer or a tester, understand why visual testing is important for web applications and how we can leverage it to write better...
