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.

Technical requirements

Cypress can be installed as a standalone application on your computer and can be run on a machine that has at least 2 GB of RAM and that meets any of the following operating system requirements:

  • macOS 10.9 and above (64-bit only)
  • Linux Ubuntu 12.04 and above, Fedora 21, and Debian 8 (64-bit only)
  • Windows 7 and above

In order to use Cypress on one of the operating systems listed here, Node.js 8 or above must be installed first. Node.js is a JavaScript runtime environment that allows JavaScript code to be run outside the browser. Installing Node.js installs npm, which allows us to install JavaScript packages from https://www.npmjs.com/. npm is the default package manager for Node.js, and users can either use it or use third-party package managers such as Yarn. In this section, we will install Cypress on both macOS and Windows operating systems.
