GoTo Test Method Source not possible in VS2022 and VS2026

[Gordrin]

Hi, I am not sure if its a TUnit or Visual Studio problem.

The Test Explorer finds all Tests and is able to run them. But I cannot jump to a test method using the test explorer. In the Test Details it seems the Information about the source code (File and Line) is missing. It is working for all xunit tests.

Is this a known bug?
Is it something locally I might miss?

Another sad thing about Visual Studio Enterprise is the missing Live Unittesting Feature for TUnit Tests. But that should 100% be a Visual Studio issue isn't it?

Thank you

If you view the source generated code for a test, does it show the file path and line number there ?

It seems like this is missing
