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.

Comparing Cypress and Selenium WebDriver

It is easy to fall into the trap of making assumptions that Cypress is a replacement for Selenium WebDriver and that its use could render Selenium WebDriver completely obsolete in the world of testing automation. While it is simple to directly assume that either Cypress is better or superior to Selenium or the other way round, this thinking is flawed and is incorrect in most instances.

In this section, we will cover why Cypress is unique and how its purpose is more complementary to Selenium WebDriver than supplementary. The following sections outline some of the differences between Selenium WebDriver and Cypress.

Browser driver

Cypress utilizes a custom universal driver for all the browsers that it supports, while on the other hand, Selenium WebDriver utilizes different drivers for each of the different browsers that it supports. The ability to use a universal driver for all the browsers means that on installation, we can run our tests...
