ASP.NET Core 5 and Angular - Fourth Edition

By: Valerio De Sanctis

Overview of this book

Learning full-stack development calls for knowledge of both front-end and back-end web development. ASP.NET Core 5 and Angular, Fourth Edition will enhance your ability to create, debug, and deploy efficient web applications using ASP.NET Core and Angular. This revised edition includes coverage of the Angular routing module, expanded discussion on the Angular CLI, and detailed instructions for deploying apps on Azure, as well as both Windows and Linux. Taking care to explain and challenge design choices made throughout the text, Valerio teaches you how to build a data model with Entity Framework Core, alongside utilizing the Entity Core Fluent API and EntityTypeConfiguration class. You’ll learn how to fetch and display data and handle user input with Angular reactive forms and front-end and back-end validators for maximum effect. Later, you will perform advanced debugging and explore the unit testing features provided by xUnit.net (.NET 5) and Jasmine, as well as Karma for Angular. After adding authentication and authorization to your apps, you will explore progressive web applications (PWAs), learning about their technical requirements, testing, and converting SWAs to PWAs. By the end of this book, you will understand how to tie together the front end and back end to build and deploy secure and robust web applications.

ASP.NET Core and Angular Unit Testing

Unit testing is the name given to a method of software testing that helps to determine whether the isolated modules of a program (units) are working correctly. After the various units have been verified, they can be merged together and tested as a whole (integration testing and system testing) and/or released in production.

Given this definition, it's pretty easy to understand the importance of properly defining and isolating the various units. These are the smallest testable parts of our software, featuring a few inputs and a single output. In Object-Oriented Programming (OOP), where the program's source code is split into classes, a unit is often a method of a super, abstract, or derived class, yet it can also be a static function of a helper class.

Although they've become a de facto standard for high-quality projects, unit tests are often underestimated by most developers and project managers who are eager to speed up...
