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.

Summary

In this chapter, we learned how to classify tests in Cypress by understanding what passing, failing, and skipped tests mean and how Cypress views and represents tests in the test runner and command log. We also learned about the structure of the test file and the acceptable file extensions for Cypress tests. We then wrote our first practical tests, which tested that a Todo application can add, delete, and mark a Todo as completed. The highlight of this chapter was learning how Cypress watches for file changes and how we can carry out our assertions in Cypress either by explicitly asserting our test subjects or implicitly asserting them. By completing this chapter, you know how to write a basic test in Cypress by working with elements and understanding the assertions that are available. In the next chapter, we will learn how to debug running tests in Cypress and the tools that we can use for that purpose.
