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.

Visual testing

Whether you are a web developer or a tester, there is a need to ensure that the application under development retains the look and feel that was intended at project conception. As a developer, you may want to verify that there are no visual aspects about your application that changed between releases. As a tester, you may want to validate that the application's user interface remains consistent between releases and is consistent with the design.

Functional testing can be used to check for visual aspects, such as validating that a button or an input box is present. However, this may involve a lot of code being written and, most of the time, will not allow you to test every aspect of the application, such as CSS changes when we use it to validate user interface elements. Visual testing is the ability to verify visual aspects of an application's user interface and ensure that they are consistent with the expectations.
