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 1: Installing and Setting Up Cypress

Cypress is an end-to-end test automation framework built and engineered for modern web applications. It focuses on eliminating inconsistencies in tests by ensuring that you can write, debug, and run tests on the browser without needing additional configuration or additional packages. Cypress works as a standalone application and can be installed on macOS, Unix/Linux, and Windows operating systems either using Hyphenate applications or command-line tools. Cypress was mainly built for developers who write their applications using JavaScript because it can be used to test all applications that run on a browser. In this chapter, we are going to cover the following topics:

  • Installing Cypress on Windows
  • Installing Cypress on macOS
  • Installing Cypress via direct download
  • Opening the Cypress test runner
  • Switching Cypress browsers
  • Adding npm scripts
  • Running Cypress tests

By the end of this chapter, you will...
