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 11: Exercise – Stubbing and Spying XHR Requests

Before we get started on this chapter, you need to understand why we need to stub or spy requests and methods, and to do this, you will need an understanding of Cypress requests and how to test individual methods. The previous chapters have presented extensive knowledge on how you can easily get started on Cypress, and we have covered concepts relating to network requests and functional testing. In this chapter, we will be building on the concepts that we have gained in the previous chapters with the focus being a hands-on approach by use of examples and exercises.

We will cover the following key topics in this chapter:

  • Understanding XHR requests
  • Understanding how to stub requests
  • Understanding how to spy on methods in a test

Once you've worked through each of these topics, you will be ready to get started on visual testing with Cypress.
