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 9: Advanced Uses of Cypress Test Runner

Before we get started on advanced uses of the Test Runner, it is crucial that you understand how Cypress works, the role of the Test Runner, and how tests are executed in the Test Runner. This chapter builds on the knowledge of Cypress that you have acquired in the previous eight chapters and will focus on assisting you to understand the advanced functions of the Test Runner that we have not yet explored in this book.

Throughout this chapter, we will utilize the Test Runner and learn how to write better tests by making use of the built-in functions of the Test Runner. By learning how to use the Test Runner, we will have a deeper understanding of how tests run, what happens when they are failing, and how they can be improved. We will cover the following key topics in this chapter:

  • Understanding the instrument panel
  • Understanding the Selector Playground
  • Test Runner keyboard shortcuts
