Right-click a test and click debug causes the indicator to spin forever.

[tarekahf]

Steps to reproduce:

1. Start VS Code
2. Run the command to create NUnit Test

dotnet new unit --framwork net5.0

3. Right-click a test, and click debug.

The wheel will spin forever, and I see the following in the output:

Executing dotnet test --no-build --logger "trx;LogFileName=C:\Users\username\AppData\Local\Temp\2\test-explorer-v2Ocg1\0.trx" --filter "FullyQualifiedName=tests.Tests.Test1" in c:/Projects/Jira/some-folder/tests

Please help to resolve this issue.

Note that with xUnit it works fine. The debug from the tree works fine without any problem.

I notice this debugging feature is in Alpha, according to the "Details" but yeah, debugging never works for me (I'm using NUnit also)

[dviererbe]

I wanted to debug a .NET 7 xUnit Test and I had the same problem. I could attach the debugger manually.

Workaround:
On Windows: Search for a process called "testhost.exe" in the TaskManager and use the PID to attach the debugger. After the process stops, the spinning will stop too.

Same issue here.

• PackageReference Include="nunit" Version="3.12.0"
• VS Code Version: 1.77.0
• TargetFramework net6.0
• SDK Version 6.0.406

Workaround

that worked for me is to start debugging by clicking on Debug Test in the code file view:
