Grouping tests works in Visual Studio but not in Rider

[arialdomartini]

Tests in Visual Studio are properly grouped:

while in JetBrains Rider they are always displayed as a flat list:

Rider does provide some options to control the grouping logic, but they don't seem to have an effect:

I also noticed that "Go to source" does work on Visual Studio but not in Rider. I'll be happy to open a separate issue, if this helps. Of course, I will be also happy to contribute fixing this, but I'm afraid I need some time to get acquainted with the code.

Visual Studio, dotnet test, Ionide, and I'm pretty sure Rider all use the VSTest json RPC server (or the newer Microsoft.Testing.Platform equivalent) for discovering and running tests (example project).

For either VSTest or MTP, it's YoloDev.Expecto.TestSdk that maps Expecto into the test platform.

I would expect all clients of the test platform to be getting the same info from YoloDev.Expecto.TestSdk, so if just one client is broken then it's probably a bug in that particular client.

Expecto can't do anything about this. Neither can YoloDev.Expecto.TestSdk (which very much seems to report test case names correctly). It's an issue with Rider itself, as far as I can tell.
