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.

Modifying TDD tests

In the previous section, we looked at how TDD tests are structured and the rationale through which they are developed to suit the application under development. As we mentioned earlier, we will not go into the details of how we will develop the application. Instead, we will focus on how to integrate testing into the application under development. The application being referenced here is available in this book's GitHub repository (https://github.com/PacktPublishing/End-to-End-Web-Testing-with-Cypress/tree/master/chapter-06/).

In this section, we will use the TDD tests that we created in the previous section. The TDD tests that we will be building on are responsible for testing the defined requirements of the application, which are as follows:

  • Adding new todo items
  • Deleting todo items
  • Viewing added todo items
  • Viewing a count of added todo items

Now that we have written the tests, we will add features to the application as we modify...
