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 4: Writing Your First Test

Before you start this chapter, you need to have an understanding of how Cypress tests are run, different Cypress commands, how to set up Cypress, running Cypress on the command line, and how to use the test runner to open Cypress tests. This information was covered in the first three chapters, and will help you better understand the fundamentals that we will be building on in this chapter when writing our first test.

In this chapter, we will cover the basics of creating test files and writing a basic test, before we move on and write more complicated tests and assert various elements using Cypress.

We will cover the following topics in this chapter:

  • Creating test files
  • Writing your first test
  • Writing practical tests
  • Cypress' auto-reload feature
  • Cypress assertions

By completing this chapter, you will be ready to learn how to debug running tests using the test runner.
