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.

Exploring test setup and teardown

As tests can be quite long and contain a lot of repetitive actions, TestCafe has a way to optimize this with test setup and teardown.

Setup is usually done by executing a number of specific functions (also known as hooks) before a fixture or test starts (including fixture.before, fixture.beforeEach, and test.before).

Teardown is usually done by executing a number of specific functions after a fixture or test is completed (including fixture.after, fixture.afterEach, and test.after).

There are six methods for using hooks in TestCafe.

The first two (fixture.before and fixture.after) do not have access to the tested page and thus should be used to perform server-side operations, such as preparing the tested application's server or pre-creating some test data in the database:
