Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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 do™, 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.

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.

My Top N Favorite Plugins and Tools for Developers
If you use NSubstitute (the best mocking .NET framework), then you have to install this small yet useful plugin right now. It kindly generates mocks and Arg.Is / Arg.Any.

Optimizing C# code analysis for quicker .NET compilation
Several well-known NuGet packages such as xUnit.net, FluentAssertions, StyleCop, Entity Framework Core, and others include by default a significant number of Roslyn analyzers. They help you adhere to the conventions and best practices of these libraries.

Integration testing in Umbraco 10+: Validating document types
Most of my rules apply to document types, so let's build some tests for document types. We start by creating a new test class and a new test function and getting a list of all document types. This test is created using xUnit and FluentAssertions:

Fluent Assertions: Fluently Assert the Result of .NET Tests
This library extends the traditional assertions provided by frameworks like MSTest, NUnit, or XUnit by offering a more extensive set of extension methods. Fluent Assertions supports a wide range of types like collections, strings, and objects and even allows for more advanced assertions like throwing exceptions.

FluentValidation in .NET
You can verify the functionality of this validator by writing the following tests (using xUnit):

Running a XUnit test with C#?
The git repo has other runners. AssemblyRunner appears to be the best fit for an already compiled tests project, but there is a runner that can be wrapped into an MSBuild task for example.

Setting up a simple testing project with C#
At this point you're going to see a familiar screen asking you to select a project. Here we're looking for a test project. By default, Visual Studio gives you access to 3 different testing frameworks based on your choice of project. These are MSTest, XUnit and NUnit. Ultimately, all 3 of these testing accomplish the same thing, and I've worked with all of them at various points in my career. The difference is mainly in exact syntax and documentation. Although, it's generally considered that MSTest is a little "older" than NUnit or XUnit, so I tend to see it less now. For the purposes of this demo, I'm going to go with NUnit:

Integration tests for AWS serverless solution

-
Test-Driven Development
Use a testing framework: Utilize a testing framework like NUnit, xUnit, or MSTest to create, organize, and run your tests. These frameworks provide a consistent way to write tests, generate test reports, and integrate with continuous integration tools.
What are some alternatives?
Moq - Repo for managing Moq 4.x [Moved to: https://github.com/moq/moq]
Shouldly - Should testing for .NET—the way assertions should be!
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.
NUnit - NUnit Framework
FakeItEasy - The easy mocking library for .NET
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.
