A while back I wrote an article on this subject where you have NUnit tests not running in Visual Studio and how to fix it. In this blogpost I will share the same soluition expect with xUnit since it involves some other packages and error messages it might not be clear that it is a related issue.

Background:

Let's say we have a .NET Class Library project and we've installed the following packages:

PM > Install-Package xunit
PM > Install-Package xunit.runner.console
PM > Install-Package xunit.runner.visualstudio

Next we create an example test and this pops up in the Visual Studio Test Explorer as expected.

The issue:

When we run our test we get the following results:

Test run finished: 0 Tests (0 passed, 0 Failed, 0 Skipped)

And if you look in the Tests output we see the following message:

"Microsoft.VisualStudio.TestPlatform.ObjectModel.TestPlatformException: Could not find testhost"

The solution:

What you need to do is install an additional package:

PM > Install-Package Microsoft.NET.Test.Sdk

And you're all good! ✅ More info can be found in the related article.

Cheers friends! ❤️
