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

1.1 Angular testing overview
- Components —Chunks of code that you can use to encapsulate certain functionality that you can then reuse throughout the application. Components are types of directives (see next bullet), except they include a view or HTML template.
- Directives —Used to manipulate elements that exist in the DOM or can add elements to or remove them from the DOM. Examples of directives included with Angular are
ngFor
,ngIf
, andngSh
ow
. - Pipes —Used to transform data. For example, say you want to turn an integer into currency. You would use a currency filter pipe to turn 15 into $15.00.
- Services —Although services technically don’t exist in Angular, the concept is still important. You’ll use services to fetch data and then inject it into your components.
- Routing —Allows users to navigate from one view to the next as they perform tasks in the web application.
