Unit Test fails to run on solution based on Helix Visual Studio Templates - sitecore

Question

my project solution is based on Sitecore Helix Visual Studio Templates by Ander's Laub. Im trying to write Unit tests using XUnit, but none of the tests are running and not even failing.
For test projects, I have tried using Project based on Class Library(.NET Framework), Projects based on Sitecore Helix Visual Studio Templates by Ander's Laub.
Packages used:
XUnit(2.4.1)
XUnit.Runner.VisualStudio(2.4.3)
XUnit.Runner.Console(2.4.1)
Framework: .NET 4.8
Visual Studio 2019: v16.8.5
The output im getting:
Since Im not able to post images, here is the Text Explorer details:
Group Summary
Linde.Foundation.SitecoreExtensions.Tests
Tests in group: 1

DemoTests.cs
public class DemoTests
{
[Fact]
public void DemoTestForPassingOnly()
{
double expected = 5;
double actual = 4;
Assert.Equal(expected, actual);
}
}
Test Run Output window:
ProjectData: Could not find project with GUID 09fe023c-998c-4a4c-a896-bc27884e7aaf

I have tried building a separate Console Application with Tests project to make sure whether this is a Visual Studio Issue, but it is running/failing/passing inside the console application, but not inside the Sitecore Project.
Do I have to configure the solution differently in order for the Tests to run successfully?

Answer 1

For simple unit tests using xunit I only have those references in my package :
<?xml version="1.0" encoding="utf-8"?>
<packages>
<package id="xunit" version="2.4.1" targetFramework="net462" />
<package id="xunit.abstractions" version="2.0.3" targetFramework="net462" />
<package id="xunit.analyzers" version="0.10.0" targetFramework="net462" />
<package id="xunit.assert" version="2.4.1" targetFramework="net462" />
<package id="xunit.core" version="2.4.1" targetFramework="net462" />
<package id="xunit.extensibility.core" version="2.4.1" targetFramework="net462" />
<package id="xunit.extensibility.execution" version="2.4.1" targetFramework="net462" />
<package id="xunit.runner.console" version="2.4.1" targetFramework="net462" developmentDependency="true" />
<package id="xunit.runner.visualstudio" version="2.4.1" targetFramework="net462" developmentDependency="true" />
</packages>
So I believe the XUnit.Runner.VisualStudio(2.4.3) should be 2.4.1.
Then a simple test could look like that
using aProject.Foundation.Utilities.Extensions;
using Xunit;
namespace aProject.Foundation.Utilities.Tests
{
public class ExtensionsTests
{
public class StringExtensionTests
{
[Theory]
[InlineData("some awesome string")]
[InlineData(" some awesome string ")]
public void Should_returnValidSlug_When_passingStringWithSpaces(string name)
{
Assert.Equal("some-awesome-string", name.ToSlug());
}
}
}
}
