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.

Resources to learn the F# ecosystem
Unit testing: I personally use FsUnit, specifically FsUnit.Xunit. There's some other libraries like Expecto and Hedgehog (property testing), but I haven't found a reason to use them. I recently started experimenting a little with Hedgehog. FsUnit integrates well into Visual Studio, since it sits nicely on top of NUnit and xUnit, and it's done everything I've needed so far.

API: Go, .NET, Rust
Yes, it does feel like some of the "standard stuff" in other more nuanced languages are missing (especially miss AutoFixture ngl). Some of those are a conscious decison by the golang team for example.

Integration Testing Postgres Store
Our first test is very easy, I like to name my tests as MethodName_GivenCondition_ShouldExpectedResult to follow the pattern, I have added GetById_GivenRecordDoesNotExist_ShouldReturnNull and I am going to leavarage excellent AutoFixture to get a new Guid as parameter. For this test we don't need arrange part, we would skip to the act and then assert. For Assertion I am going to use FluentAssertions. For this test we need to assert the returned result is null.

Setting up a simple testing project with C#
The next test to talk about, is that if this was a bank, we would have multiple customers, who can hold multiple accounts that we need to calculate the interest for. You could manually construct these objects if you want, but I'm going to use a package called AutoFixture to make life easier.

AutoFixture Tips and Tricks
AutoFixture is an amazing library that simplifies the process of creating test data in .NET. If for some reason you don't use this fantastic tool, it's time to consider it. Today, I'm going to share some tips for using AutoFixture that will be beneficial for developers of all skill levels. Let's get started!
- Integration tests without API dependencies with ASP.NET Core and WireMock.Net

Reduce your tests cognitive complexity with AutoFixture
Ensuring that your test is still readable and not bloated by the setup of those variables may be quite a challenge but hopefully no more with AutoFixture, let's see how!

Practical complex data for unit testing
One neat library for creating and generating test data is AutoFixture. The creators describe it as follows:

14 .NET packages I always recommend
First time I heard of Bogus, looks interesting, been using AutoFixture for those will definitely take a look at it.
- LPT: There is a library called Bogus, you should know it exists much earlier than I did in my career.
What are some alternatives?
xUnit - xUnit.net is a free, open source, community-focused unit testing tool for .NET.
Bogus - :card_index: A simple fake data generator for C#, F#, and VB.NET. Based on and ported from the famed faker.js.
FsCheck - Random Testing for .NET
NSubstitute - A friendly substitute for .NET mocking libraries.
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/)
FakeItEasy - The easy mocking library for .NET
NUnit - NUnit Framework
Moq - Repo for managing Moq 4.x [Moved to: https://github.com/moq/moq]
Fine Code Coverage - Visualize unit test code coverage easily for free in Visual Studio Community Edition (and other editions too)
NBuilder - Rapid generation of test objects in .NET
Canopy - f# web automation and testing library, built on top of Selenium (friendly to c# also)
