无法在 Visual Studio 2019 for Mac 上运行 .NET Core 3.1 测试项目

Question

I am having trouble running tests from inside VS. I created the simplest solution with just one NUnit Test project from the template and one test with Assert.IsTrue(true).

Here are the NuGet packages I added to the project with their versions in case it helps:

• Microsoft.NET.Test.Sdk 16.8.0
• NUnit 3.12.0
• NUnit3TestAdapter 3.17.0

Here is the output I get when running the tests from the command line using dotnet test [projName]:

Determining projects to restore...
Restored /Users/OpenMinder/DevTraining/Test/Test.csproj (in 331 ms).
  Test -> /Users/OpenMinder/DevTraining/Test/bin/Debug/netcoreapp3.1/Test.dll

A total of 1 test files matched the specified pattern.

But whenever I try to run them from VS for mac I get the following behaviour:

1. The tests names don't show up in the panel

2. The test run doesn't finish

3. I get the following error in the output:

Anybody has any idea of what else I can try?

Let me know if you need any more information.

Answer 1

Maybe this helps someone, I managed to solve this now, I created a symbolic link in the past to fix something else and I forgot about that.

I fixed this by removing that link with this command:

rm /usr/local/bin/dotnet 

Now I am able to use both VS Code and VS for Mac.

Thanks!
