Angular Test-Driven Development - Second Edition

Enhance your testing skills to build powerful and fault-free applications in Angular v4.

This book is for developers who have experience with Angular but want to understand the wider context of when, why, and how to apply testing techniques and best practices to create quality clean code. To get the most out of this book, you should have a good understanding of HTML and JavaScript and a basic understanding of Angular.

This is a complete guide that shows you testing techniques with Karma that will help you perform unit testing and end-to-end testing with Protractor. It will show you how to optimize your Angular development process using TDD techniques and ensure your final project is free of bugs. All examples in this book are based on Angular v2 and are compatible with Angular v4.

We start by reviewing the TDD life cycle, TDD in the context of JavaScript, and various JavaScript test tools and frameworks. You will see how Karma and Protractor can make your life easier while running JavaScript unit tests. We will enable you to build a test suite for an Angular application and build a testable medium-to-large scale Angular application by handling REST API data.

Building on the initial foundational aspects, we move on to testing for multiple classes, partial views, location references, CSS, and the HTML element. In addition, we will explore how to use a headless browser with Karma. We will also configure a Karma file to automate the testing and tackle elements of Angular (components, services, classes, and broadcasting) using TDD.

Finally, you will find out how to pull data using an external API, set up and configure Protractor to use a standalone Selenium server, and set up Travis CI and Karma to test your application.
