Setting up a simple testing project with C#
In terms of mocking there are several frameworks you can use, but I've mainly relied on Moq and NSubstitute. Within this demo, I'm going to use NSubstitute as I've found it a little easier to use.

What if writing tests was a joyful experience
Or you just run into bullshit like https://github.com/Moq/moq4/issues/173
- Moq.NET Mocking framework [C#]
-
Dependency injection
Now to the real benefit of DI: If you are testing a method in your application that calls the ReservationRepository.GetReservation() method, you can use a library like Moq to simply "mock" a class that uses the IReservationRepository interface and define the return result of the GetReservation() method. Pass the mocked class into the constructor of the class you are testing.

A Tale of 2 Codebases (Part 2 of 4): Testability
Both projects use similar testing infrastructure. I write unit tests in C# using XUnit.net. I frequently use mock objects in testing, and MOQ is my tool of choice. I utilize continuous testing and coverage analysis through Rider. I do not have specific objectives for code coverage. When writing complicated algorithms, I frequently shoot for 100% coverage of the algorithm. I test simple properties inconsistently, and frequently do not test guard clauses.

What's your go-to unit testing tool?
But the reality is that I don't really write my tests with it. Toss on the MSTest attributes as needed of course. But all the testing code itself is FluentAssertions with a bit of Moq. (Though I find rarely need to use Moq/mocking anymore -- scandalous, I know.)

What am I missing about interfaces?
a. you might do so purely out of argo cult, i.e. because someone told you this was the right thing to doâ„¢, and that's a silly exercise. b. you could also be doing this for a good reason: to use the interface with a mocking tool like NSubstitute

The Moq-gate: You Either Die a Hero...
When comparing it to one of its most well-known alternatives, NSubstitute, which has "only" reached 85.6 million downloads, it is fair to say that Moq is the most widely used mocking library in the .NET ecosystem.

Since v4.20, Moq is harvesting email addresses
Maintainer rejected the PR. They have temporarily disabled the integration in https://github.com/moq/moq/pull/1375 but kept the SponsorLink project reference in the source code. It seems like their intent is to re-enable the integration at a later point :(
NSubstitute [0] might be an alternative. Or to fork Moq pre-4.20.

Dot net libraries/tools that are usefull in many projects
Another nice mocking framework is NSubstitute https://nsubstitute.github.io/
What are some alternatives?
FakeItEasy - The easy mocking library for .NET
AutoFixture - AutoFixture is an open source library for .NET designed to minimize the 'Arrange' phase of your unit tests in order to maximize maintainability. Its primary goal is to allow developers to focus on what is being tested rather than how to setup the test scenario, by making it easier to create object graphs containing test data.
Bogus - :card_index: A simple fake data generator for C#, F#, and VB.NET. Based on and ported from the famed faker.js.
AutoMoq - Auto mocking provider for Moq.
NUnit - NUnit Framework
Rhino Mocks
Fluent Assertions - A very extensive set of extension methods that allow you to more naturally specify the expected outcome of a TDD or BDD-style unit tests. Targets .NET Framework 4.7, as well as .NET Core 2.1, .NET Core 3.0, .NET 6, .NET Standard 2.0 and 2.1. Supports the unit test frameworks MSTest2, NUnit3, XUnit2, MSpec, and NSpec3.
