Description
The Angular 2 framework is great for building large-scale web applications that can be maintained and extended. And when building enterprise-level apps, testing is vital to the development process. Testing improves the quality of code and reduces maintenance, saving both time and money. Even though testing is crucial, it’s sometimes neglected since there are few established resources and standards when it comes to modern JavaScript web applications. Developers who know how to build and leverage tests are highly valued by their clients and companies.
Testing Angular Applications is an example-rich, hands-on guide that gives the real-world techniques needed to thoroughly test all parts of Angular 2 applications. The book starts with an introduction to Angular 2, TypeScript, testing fundamentals, and the testing frameworks and tools used in the book. Next, it explains how to set-up an Angular 2 environment, including TypeScript and the Angular 2 dependencies. The reader will then create their first component. The second part of the book focuses on the most important concepts of Angular 2, such as testing components, directives, pipes, services, and routing. This book will allow readers to confidently write unit and endto-end tests for Angular 2 applications and TypeScript.
