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.

Do you guys mock everything in your Unit Tests?

organizing testing projects
Are you familiar with "snapshot testing" tools such as Verify that store expected output in files. It's still unit testing.

Add persisted parameters to CLI applications in .NET
We can use Verify to perform snapshot testing and check for the correct output of the program. In order to make things easier and simplify working with process output capturing and invocation, I used CliWrap.

In EF Core every foreach is a potential runtime error that can't be properly fixed
You will have to write extra code to set up a code base to get it started (there's always a large initial cost in getting things set up, and you'll be writing code that helps get the state of your application setup), but I can assure you that our team paid the initial tax and the only reason our tests change now is because of requirements changes (and maybe sometimes because the testing tools we use like Verify have some breaking changes in behavior when we upgrade). Otherwise, it helps us identify issues in our code, particularly when we do library upgrades or change to a different library. Again, our tests do not change when we completely reimplement anything, just when the external contract changes. We just get to refactor/reimplement and have confidence that the old behavior stays the same. And then you get to hook up a benchmark to your tests and, if your reason for refactoring was performance reasons, you can show that it was effective.

Perfect Replayability
I assume this means you can take something like this, combine it with Snapshot/Approval testing (link to a library I have used), and then you have some quick-to-generate tests that help guard against regressions (even visual ones) by say:

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.
-
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.

NUnit vs. XUnit vs. MSTest: Comparing Unit Testing Frameworks In C#
MSTest is the default test framework that is shipped along with Visual Studio. The initial version of MSTest (V1) was not open-source; however, MSTest V2 is open-source. The project is hosted on GitHub. Like other test frameworks, it can also be used for data driven testing. You can download MSTest V2 from Nuget.org.

Most Complete MSTest Framework Tutorial Using .Net Core
Open-Source – MSTest V2 is open-source, and the project is hosted on GitHub. The public repositories of the MSTest V2 are Microsoft/testfx and Microsoft/testfx-docs. Since the project is open-source, it allows contributions from the community.

snapshooter - Snapshooter is a snapshot testing tool for .NET Core and .NET Framework
Moq - Repo for managing Moq 4.x [Moved to: https://github.com/moq/moq]
Shouldly - Should testing for .NET—the way assertions should be!
xUnit - xUnit.net is a free, open source, community-focused unit testing tool 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.
vstest - Visual Studio Test Platform is the runner and engine that powers test explorer and vstest.console.
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.
Fine Code Coverage - Visualize unit test code coverage easily for free in Visual Studio Community Edition (and other editions too)
