Testing Angular Applications

**Summary** __Testing Angular Applications__ is an example-rich, hands-on guide that gives you the real-world techniques you need to thoroughly test all parts of your Angular applications. By the end of this book, you'll be able to confidently write unit and end-to-end tests for Angular applications in TypeScript. Foreword by Brad Green, Google. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. **About the Technology** Don't leave the success of your mission-critical Angular apps to chance. Proper testing improves code quality, reduces maintenance costs, and rewards you with happy users. New tools and best practices can streamline and automate all aspects of testing web apps, both in development and in production. This book gets you started. **About the Book** __Testing Angular Applications__ teaches you how to make testing an essential part of your development and production processes. You'll start by setting up a simple unit testing system as you learn the fundamental practices. Then, you'll fine-tune it as you discover the best tests for Angular components, directives, pipes, services, and routing. Finally, you'll explore end-to-end testing, mastering the Protractor framework, and inserting Angular apps into your continuous integration pipeline. **What's inside** * Getting to know TypeScript * Writing and debugging unit tests * Writing and debugging end-to-end tests with Protractor * Building continuous integration for your entire test suite **About the Reader** This book is for readers with intermediate JavaScript skills. **About the Author** **Jesse Palmer** is a senior engineering manager at Handshake. **Corinna Cohn** is a single-page web application specialist. **Mike Giambalvo** and **Craig Nishina** are engineers at Google. **Table of Contents** 1.

It improves the quality of code and reduces maintenance, saving both time and money. But testing is sometimes neglected since there are few established resources and standards when it comes to testing modern Angular web applications. Testing Angular Applications is an example-rich, hands-on guide that gives the real-world techniques needed to thoroughly test all parts of Angular applications. The book starts with an introduction to Angular , TypeScript, testing fundamentals, and the testing frameworks and tools used in the book. Next, it explains how to set-up an Angular environment, including TypeScript and the Angular dependencies. The reader will then create their first component. The second part of the book focuses on the most important concepts of Angular, such as testing components, directives, pipes, services, and routing. This book will allow readers to confidently write unit and end-to-end tests for Angular applications and TypeScript. Testing is vital to the development process.
