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.

How do you Unit Test a WebAPI? What do you test?
So what I usually do is: • Unit test underlying (public) services and application ‘core’ • Integration test (or w/e you call it) an entire functionality flow, by sending in ‘real’ requests on one end, and locally mocking/stubbing the application ‘edges’ that supply the response data. WireMock for requests to external services, H2 or Testcontainers for database.

EF Core In-Memory DB (for testing) does not allow List<int> property even though this is something Postgres does. How would I go about testing this?
I'd use testcontainers to spin up an instance of Progress and run against the actual thing. That way you get the benefit of testing against the actual database, but also that you don't have to set up a bunch of stuff locally.
Not every db support array as primitive, if you want to write integration tests and you have access to docker I suggest you testcontainers.

Does anyone have a good functional (integration? end to end?) automated Web API testing setup?
There is a rope which can help with this task: https://github.com/HofmeisterAn/dotnet-testcontainers

Integration testing with EF Core, part 2
Dotnet.Testcontainers also comes with some built-in classes that wraps various services, one of these classes actually wraps a SQL Server Docker container and there are few more that covers the most common databases e.g.
-
End to end testing is confusing
You should also check out Docker, especially TestContainers. That way you can spin up databases (and other dependencies) on the fly and do operations on them. This means that you don't need to "fake" a database, as you will have access to a new one.

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:

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?
FluentDocker - Use docker, docker-compose local and remote in tests and your .NET core/full framework apps via a FluentAPI
Shouldly - Should testing for .NET—the way assertions should be!
NUnit - NUnit Framework
WireMock.Net - WireMock.Net is a flexible product for stubbing and mocking web HTTP responses using advanced request matching and response templating. Based on the functionality from http://WireMock.org, but extended with more functionality.
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.
