The test projects have to be .NET (Core) or .NET Framework; .NET Standard can't be used as a test project, since it can't be run on its own, but any code in a .NET Standard library can be tested from a .NET (Core) or .NET Framework test project. TL;DR Adding the adapter and Microsoft.NET.Test.Sdk version 17.8.0 or greater to your NUnit test projects will also enable the dotnet test command for .NET Core projects. Any tests using the new style CSPROJ format, either .NET Core or .NET 4.x, need to add a PackageReference to the NuGet package Microsoft.NET.Test.Sdk.

FAQ Why can't my tests target .NET Standard Visual Studio and VSTest require that the tests target a specific platform. .NET Standard is like a Portable library in that it does not target any specific platform, but can run on any supported platform. Microsoft decided that your tests should be compiled to target a platform so they know which platform to run your tests under and you get the behavior you expect for the platform you are targeting. You can however target multiple platforms in your tests and compile and run each from the command line. It still only runs one platform from Visual Studio, but I would hope that is being worked on. I haven't tested 15.3 yet. It is similar to a console application, it cannot be .NET Standard, it must target a platform, .NET Core or .NET Framework. This limitation is the same for all test adapters including xUnit and MSTest2. My tests aren't showing up in Visual Studio 2022 or later Are you using the NuGet adapter package?

Have you restarted Visual Studio? It is still a bit temperamental. Are you doing integration testing with Asp.Net Core WebApplicationFactory and using minimal API, and it complains about missing testhost.deps.json? Then you're accessing the wrong Program class in your WebApplicationFactory. Fix it by adding a code line at the end of the Program.cs file, and verify that your WebApplicationFactory is actually using this Program class: public partial class Program { } My tests multi-target .NET Core and .NET Framework, why can't I run both in Visual Studio This was a limitation in earlier versions of Visual Studio, but is fixed in Visual Studio 2022. If you must run an earlier version and have this issue, you can run specific tests using the --framework command line option of dotnet test How do I produce a test results file dotnet test can generate an NUnit3 test result file by adding a runsettings property. The property to add is TestOutputXml. This generation is done using the NUnit Engine report service, and produce the same result as the NUnit3-console. This is available through the NUnit3TestAdapter. You run it by adding the setting on the command line (or in a runsettings file): dotnet test -- NUnit.TestOutputXml=yourfoldername The folder is relative to a base folder determined by the OutputXmlFolder settings, or you can use an absolute path.
