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.

Understanding errors on a test runner

In this section, we will dissect Cypress errors on the test runner, thus unpacking the contents of the errors thrown by Cypress and how to interpret them. We will cover different types of information that are present in Cypress errors, including the error name, the error message, the code frame file, the stack trace, the print to console option, and learn more. Understanding errors in Cypress will not only help us write better tests but also guide us through the debugging process when our tests fail.

Cypress excels when it comes to logging exceptions in a test failure event. Cypress not only logs information about which tests are failing but goes ahead and drills into specific information about the error that was encountered. Errors such as successful test executions are visible on the Cypress command log and provide descriptive pieces of information that could have led to the error being encountered. At times, Cypress even prints suggestions...
