Web Development with Blazor

By: Jimmy Engström

Overview of this book

Blazor is an essential tool if you want to build interactive web apps without JS, but it comes with its own learning curve. Web Development with Blazor will help you overcome most common challenges developers face when getting started with Blazor and teach you the best coding practices. You’ll start by learning how to leverage the power of Blazor and explore the full capabilities of both Blazor Server and Blazor WebAssembly. Then you’ll move on to the practical part, which is centred around a sample project – a blog engine. This is where you’ll apply all your newfound knowledge about creating Blazor Server and Blazor WebAssembly projects, the inner working of Razor syntax, and validating forms, as well as creating your own components. You’ll learn all the key concepts involved in web development with Blazor, which you’ll also be able to put into practice straight away. By showing you how all the components work together practically, this book will help you avoid some of the common roadblocks that novice Blazor developers face and inspire you to start experimenting with Blazor on your other projects. When you reach the end of this Blazor book, you'll have gained the confidence you need to create and deploy production-ready Blazor applications.

Writing tests

Time to write some tests. As I mentioned earlier in the chapter, we won't create tests for the entire site; we will leave that to you to finish later if you want to. This is just to get a feel for how to write tests:

  1. Right-click and select MyBlog.Shared.Tests, then select Add | New folder. Name the folder Pages.

    This is just so we can keep a bit of a structure (the same folder structure as the project we are testing).

  2. Select the Pages folder. Press Shift + F2 to create a new Razor component and name the file IndexTest.cs. Just remember not to name it the same as the component we are testing; otherwise, it will be hard to make sure we are testing the right one.
  3. Open IndexTest.cs and add the bUnit namespace:
    using Bunit;
    using Microsoft.Extensions.DependencyInjection;
    using MyBlog.Data.Interfaces;
    using Xunit;
  4. Inherit from TestContext by adding the following code:
        public class IndexTest: TestContext
        ...
