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?
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.
- PhD'ers, what are you working on? What CS topics excite you?

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/

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:

Comprehensive Unit Testing: A Line-by-Line Approach
xUnit -> https://xunit.net/
-
CI/CD Pipeline Using GitHub Actions: Automate Software Delivery
.NET / xUnit / NUnit / MSTest

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
xUnit unit tests tool
-
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?
sharpfuzz - AFL-based fuzz testing for .NET
Shouldly - Should testing for .NET—the way assertions should be!
Moq - Repo for managing Moq 4.x [Moved to: https://github.com/moq/moq]
NUnit - NUnit Framework
MSTest - MSTest framework and adapter
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.
Bogus - :card_index: A simple fake data generator for C#, F#, and VB.NET. Based on and ported from the famed faker.js.
should - Should Assertion Library
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.
