AutoFixture VS TodoApi

Yes, it does feel like some of the "standard stuff" in other more nuanced languages are missing (especially miss AutoFixture ngl). Some of those are a conscious decison by the golang team for example.

Our first test is very easy, I like to name my tests as MethodName_GivenCondition_ShouldExpectedResult to follow the pattern, I have added GetById_GivenRecordDoesNotExist_ShouldReturnNull and I am going to leavarage excellent AutoFixture to get a new Guid as parameter. For this test we don't need arrange part, we would skip to the act and then assert. For Assertion I am going to use FluentAssertions. For this test we need to assert the returned result is null.

The next test to talk about, is that if this was a bank, we would have multiple customers, who can hold multiple accounts that we need to calculate the interest for. You could manually construct these objects if you want, but I'm going to use a package called AutoFixture to make life easier.

AutoFixture is an amazing library that simplifies the process of creating test data in .NET. If for some reason you don't use this fantastic tool, it's time to consider it. Today, I'm going to share some tips for using AutoFixture that will be beneficial for developers of all skill levels. Let's get started!

AutoFixture

Ensuring that your test is still readable and not bloated by the setup of those variables may be quite a challenge but hopefully no more with AutoFixture, let's see how!

One neat library for creating and generating test data is AutoFixture.  The creators describe it as follows:

First time I heard of Bogus, looks interesting, been using AutoFixture for those will definitely take a look at it.

This is a fairly common scenario (externalizing the authentication piece but still wanting app-local storage of some user information) that isn't well documented (we're working on that). You might try taking a look at this app by u/davidfowl that supports what you're asking about: https://github.com/davidfowl/todoapi

Good news: David Fowler has a full showcase repository TodoApi

ASP.NET Core Identity.However, most examples use Identity with the MVC/Blazor. I need to support both a SPA and a mobile app and I am not sure if that is the recommended approach here.(Perhaps I should use the backend for frontend approach like David Fowler showcases in https://github.com/davidfowl/TodoApi ?)

Pre .NET 6, there's a Startup.cs file that is used to set these up. .NET 6+ just puts them in Program.cs by default, but you can still use a Startup.cs if you'd prefer. Example of the newer template in Program.cs is here
