Running induvidual tests doesn't work - Could not find a matching test directory for test

Hello,
I have Unity project with NUnit tests. If I open Testing tab, there are not tests visible:

console output:
`
Starting extension

Executing dotnet test -t -v=q in /home/pavel/NetBeansProjects/imperium/Assets/Tests/core
`

If I click run all button, all tests runs just fine:

**If I run individuals test or test group, I will get error:**
`
[WARNING] Could not find a matching test directory for test imperium.tests.core.ConfigLoaderTest
`

I've tried to find more info what does this mean. How and where I can set "matching" test directory. But I've found nothing.

I don't know if problem is in project settings, VSCode settings, test explorer settings, vsocde bug, test explorer bug, dotnet bug or something else.
