Modern Web Development with ASP.NET Core 3 - Second Edition

By: Ricardo Peres

Overview of this book

ASP.NET has been the preferred choice of web developers for a long time. With ASP.NET Core 3, Microsoft has made internal changes to the framework along with introducing new additions that will change the way you approach web development. This second edition has been thoroughly updated to help you make the most of the latest features in the framework, right from gRPC and conventions to Blazor, which has a new chapter dedicated to it. You’ll begin with an overview of the essential topics, exploring the Model-View-Controller (MVC) pattern, various platforms, dependencies, and frameworks. Next, you’ll learn how to set up and configure the MVC environment, before delving into advanced routing options. As you advance, you’ll get to grips with controllers and actions to process requests, and later understand how to create HTML inputs for models. Moving on, you'll discover the essential aspects of syntax and processes when working with Razor. You'll also get up to speed with client-side development and explore the testing, logging, scalability, and security aspects of ASP.NET Core. Finally, you'll learn how to deploy ASP.NET Core to several environments, such as Azure, Amazon Web Services (AWS), and Docker. By the end of the book, you’ll be well versed in development in ASP.NET Core and will have a deep understanding of how to interact with the framework and work cross-platform.

You definitely should carry out unit tests for your apps. Whether you follow TDD strictly or not, they can be very useful, especially for regression tests. Most continuous integration tools out there fully support running unit tests. Just don't try to cover everything; focus on the critical parts of your app and, if time allows, then proceed to the other parts. It is unreasonable to think that we will have 100% coverage in most projects, so we need to make decisions. Mocking frameworks play an essential role here as they allow us to simulate third-party services nicely.

Automated integration tests, as we saw here, allow us to test features that aren't available in unit tests, and these cover other parts of our needs.

This chapter covered ways to test our apps, either part of them in isolation or the system as a whole. Unit tests are useful as they can ensure that our application still works the way it is supposed to, even though we are making...
