Modern Web Testing with TestCafe

By: Dmytro Shpakovskyi

Overview of this book

TestCafe is an open source end-to-end testing framework that combines unmatched ease of use with advanced automation and robust built-in stability mechanisms. This book is a comprehensive, project-based introduction to TestCafe that will show you how to use the TestCafe framework and enable you to write fast and reliable tests; plus you’ll have a proof of concept ready to demonstrate the practical potential of TestCafe. You’ll begin by learning how to write end-to-end web tests using the TestCafe syntax and features of the TestCafe framework. You’ll then go from setting up the environment all the way through to writing production-ready tests. You’ll also find out how to build a sample set of tests in a step-by-step manner and use TestCafe to log in to the website, verify the elements present on different pages, create/delete entities, and run custom JavaScript code. As you advance, you’ll delve into several stages of refactoring that will take you through the showcase setup/teardown and PageObject patterns. While this test suite is relatively simple to build, it showcases some of the most prominent features of TestCafe. Finally, this TestCafe book will show you how the tests can be run on a free and simple-to-use website, without requiring you to build and deploy your own servers or backend services. By the end of this book, you’ll have learned how to write and enhance end-to-end tests with TestCafe to solve real-world problems and deliver results.

Running tests with command-line settings

As we already learned in Chapter 3, Setting Up the Environment, when you trigger tests by executing the testcafe command, TestCafe reads settings from the .testcaferc.json configuration file, if this file exists, and then applies the settings from the command line on top of it. Command-line settings overrule values from the configuration file if they differ. TestCafe outputs information about each overridden property to the console.

Note

If the browsers and src properties are provided in the configuration file, you can omit them in the command line.

Let's review some of the main command-line settings that can be used with the testcafe command while launching the tests:
