Setting up a simple testing project with C#
You might have noticed when you were looking in NuGet, there was a package called coverlet installed into the project:

Do you use any code coverage tool on your project?
There are a lot libraries to collect code coverage, one of this one is Coverlet: https://github.com/coverlet-coverage/coverlet

Code Coverage for Build Server without Visual Studio Enterprise
We use Coverlet. You have to do some work to get it working with your tests but I have no complaints. I don't know for sure if it works with VS Community, but since it plugs into MSBuild I'm not sure how it could be gated to that.

How to define the same folder for merging test coverage?
And I would like to build a total test coverage for the solution. So, I added coverlet.msbuild to the dependencies and executed the next command from the examples of coverlet

Analyzing and enforcing .NET code coverage with coverlet
CoverletOutputFormat: The format of the report that coverlet will generate (opencover, cobertura, json). More here;
- Code coverage and warnings for modified files only

Generating Code Coverage Metrics for .NET Framework Applications
Utilize Coverletand Report Generator utilities – however, this is where its funny, because these are .NET CLI tools that need the .NET 6 SDK installed.

Code coverage for Asp.net 6 web APIs
Coverlet works really well.

Why does VSTest put the output of data collectors to GUIDed subdirectories?
However, I am hesitant to do so. Whenever it seems I have to fight the tools that are provided for me this is a likely sign that I’m Doing Things Wrong because of some fundamental misunderstandings and misassumptions on my part. I did some digging and found that VSTest by design forces the placement of data collectors’ output into GUIDed subdirectories, see Coverlet documentation, Coverlet issue #500 and VSTest issue #2378. That this is forced by design reinforces my worries that I’m doing something counterproductive.

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:
