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/

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.
What are some alternatives?
xUnit - xUnit.net is a free, open source, community-focused unit testing tool for .NET.
Moq - Repo for managing Moq 4.x [Moved to: https://github.com/moq/moq]
sharpfuzz - AFL-based fuzz testing for .NET
vstest - Visual Studio Test Platform is the runner and engine that powers test explorer and vstest.console.
Bogus - :card_index: A simple fake data generator for C#, F#, and VB.NET. Based on and ported from the famed faker.js.
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.
should - Should Assertion Library
Fine Code Coverage - Visualize unit test code coverage easily for free in Visual Studio Community Edition (and other editions too)
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.
