Angular 2 Test-driven Development, 2nd Edition

Key Features

• Learn test-driven development (TDD) in JavaScript and see its power though clear examples
• Enhance your understanding with details on Karma and Protractor, and set up an Angular2 test suit with them
• A practical guide filled examples that focus on a wide range of testing techniques in a professional Angular2 application

Book Description

This is a complete guide that shows you testing techniques with Karma to perform unit testing and end-to-end testing with Protractor. It will show you how to optimize your Angular 2 development process using TDD techniques and ensure the final project is free of bugs.

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 Angular2 application and build a testable Angular2 medium-to-large scale 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 Angular2 (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.
