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.

Installing Cypress on Windows

In this section, we will install Cypress and Node.js on Windows operating systems so that we can run our tests.

Downloading and installing Node.js

The following steps will guide you through the installation of Node.js:

  1. Visit the official Node.js website (https://nodejs.org/en/download/).
  2. Select the Windows installer option.
  3. Download the installer package.
  4. Install the Node.js package by following the instructions on the Node.js website.

Next, let's initialize the project.

Initializing the project

As a best practice, Cypress is installed in the directory where the project is located; that way, we can be sure that the Cypress tests belong to the project. In our case, we will create a folder inside Documents and call it cypress-tests, then navigate to that directory when installing Cypress. We can use the following commands in a Windows PowerShell terminal to create the cypress-tests directory and navigate to it...
