Testing Angular Applications Covers Angular 2 - Corinna Cohn - Bog - Manning Publications - Plusbog.dk

Testing Angular Applications Covers Angular 2 - Corinna Cohn - Bog - Manning Publications - Plusbog.dk

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. Key features • Testing components, directives, services and pipes • Real-world techniques • Hands-on examples • Foundation for writing advances tests • Provides code that can be reused in a production environment Audience This book is for readers with intermediate JavaScript skills and some experience with JavaScript frameworks. No experience with testing or Angular required. About the Technology Angular 2 is the latest version of the popular web application framework built by Google and its army of community contributors.

Testing Java Microservices - Jason Porter - Bog - Manning Publications - Plusbog.dk

Testing Java Microservices - Jason Porter - Bog - Manning Publications - Plusbog.dk

With traditional software unit tests, there’s never a guarantee that an application will actually function correctly in the production environment. When you add microservices, testing becomes even more tricky. Testing Java Microservices teaches readers how to write tests like unit, component, integration, container, contract, chaos, and more. Along the way, it also covers technologies like the Arquillian ecosystem, Wiremock, Mockito, AssertJ, Pact or Gatling. Finally, the book demonstrates how everything fits together into the Continuous Delivery pipeline. Key Features: · Practical hands-on guide · Writing Persistence tests · Teaches test strategies · Shows how everything fits together in the Continuous Delivery Pipeline Readers should be comfortable programming in Java. Experience with testing tools like jUnit is helpful but not required. Some experience in Java EE, Spring and Docker is also helpful. About the Technology: A microservice may consist of several, several hundred, or even several thousand of lines of code. Microservices enable programmers to isolate and scale smaller pieces of an application, rather than the entire application.
