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.

NUnit vs XUnit for .net6+ microservices
On a side note, something I would highly recommend NOT doing is using the built in assertion types for any of the test adapters. Without a doubt the hardest part of switching unit test frameworks is having to fix all your assertions which is why we use 3rd party assertions. The built-in assertions also tend to not be very feature rich and don't have the most helpful messages. We personally use FluentAssertions, but there are other options such as Shoudly or Should. I highly recommend picking one of them over the built in assertions. You will thank yourself later :)

Do you guys mock everything in your Unit Tests?
Bogus - For creating fake data Verify - Snapshot testing for .NET MELT - For testing ILogger usage Stryker - Mutation Testing for .NET TestContainers - run docker programmatically in integration tests

Scope of unit testing (karma/Jas) Boss wants unreasonable testing?
This is called mutation testing btw.

Don't target 100% coverage
Let's try it on our small example using Stryker.

Killing mutants to improve your tests
There are tools that do this automatically, stryker[2] is one of them. When you run stryker, it will create many mutant versions of your production code, and run your tests for each mutant (that's how mutations are called in stryker's' documentation) version of the code. If your tests fail then the mutant is killed. If your tests passed, the mutant survived. Let's have a look at the the result of runnning stryker against reffects-store's code:

Not sure if popular opinion: Greenfield projects should have 100% test coverage.
Mutation testing is pretty solid. Better than code coverage for sure. Using Stryker personally.
-
Seriously what are they and why does everyone hate them?
A mutation testing tool (like Stryker) runs your unit tests to verify they all pass then makes a small change (mutation) to your code and reruns the tests. At least one test should fail because the modified code should behave differently.

Relesed v1.0.0 of my pet javasscript project yesterday after hitting 100% coverage- a gesture detection library
I haven't tried it yet, but last time I researched it, this is the library that looked most promising: https://stryker-mutator.io/

What are some alternatives?
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.
sharpfuzz - AFL-based fuzz testing for .NET
GennyMcGenFace
Moq - Repo for managing Moq 4.x [Moved to: https://github.com/moq/moq]
NFluent - Smooth your .NET TDD experience with NFluent! NFluent is an ergonomic assertion library which aims to fluent your .NET TDD experience (based on simple Check.That() assertion statements). NFluent aims your tests to be fluent to write (with a super-duper-happy 'dot' auto-completion experience), fluent to read (i.e. as close as possible to plain English expression), but also fluent to troubleshoot, in a less-error-prone way comparing to the classical .NET test frameworks. NFluent is also directly inspired by the awesome Java FEST Fluent assertion/reflection library (http://fest.easytesting.org/)
MSTest - MSTest framework and adapter
Machine.Specifications - Machine.Specifications is a Context/Specification framework for .NET that removes language noise and simplifies tests.
Bogus - :card_index: A simple fake data generator for C#, F#, and VB.NET. Based on and ported from the famed faker.js.
NSubstitute - A friendly substitute for .NET mocking libraries.
GenFu - GenFu is a library you can use to generate realistic test data. It is composed of several property fillers that can populate commonly named properties through reflection using an internal database of values or randomly created data. You can override any of the fillers, give GenFu hints on how to fill them.
