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.

Writing TDD tests in Cypress

In this section, we will focus on writing TDD tests using Cypress. Throughout this section, we will build a Todo application and apply the TDD principles. First, we need to have a design in mind so that we can write proper tests and also critically think about the features of our application. The goal of this chapter will be to create an application that will add todo items, delete todo items, show added todo items, and show the count of the added todo items. A mockup of the final application is shown in the following screenshot. Every step we follow will help us achieve the mockup we desire:

Figure 6.1 – Todo application mockup

The preceding screenshot shows a mockup of our Todo application that we will be building. We will use a TDD approach with tests written in Cypress. The application will have the following features:

  • Adding new todo items
  • Deleting todo items
  • Viewing added todo items
  • Viewing...
