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.

Special debugging commands

If jumping through commands is not your thing, or you are finding it difficult to understand how travelling back in time shows you the order of execution in a test, Cypress has got your back. Cypress includes commands that are helpful for debugging and even gives you the options that you would have when using normal code debuggers. The two commands that we will be exploring in this section are as follows:

  • cy.debug()
  • cy.pause()

Using these Cypress debug commands, we can understand how to debug Cypress from the tests themselves. These two special debugging commands will allow us to directly control the debug process as we execute our tests. Having the ability to stop execution within the tests themselves gives us the advantage of only having to debug the specific sections that are throwing errors in Cypress.

cy.debug

The cy.debug() command is, by default, the debugging command that Cypress offers out of the box. The command will log...
