`dotnet watch test` no longer outputs test results in .NET 8 SDK

[onionhammer]

Prior to installing .net 8 SDK, I was able to run dotnet watch test --filter ... and I would see updated test results whenever I updated a file, now I have to re-run dotnet test, and dotnet watch test just returns

dotnet watch 🚀 Started
dotnet watch ⌚ Exited
dotnet watch ⏳ Waiting for a file to change before restarting dotnet...

If this is new to .NET 8 and still works with an older SDK, did you open an issue with the .NET team?

This looks like dotnet watch is broken in .NET 8 SDK.

Compare the .NET 6 SDK:

To the .NET 8 SDK:

Clearly the latter is just trying to run the DLL rather than run the test command, which is why it's immediately exiting with failure.

Someone has already reported this at https://github.com/dotnet/sdk/issues/34949 so closing this issue.

@bradwilson you may want to keep something open as a known tracking issue so others don't report it, it's an issue with a dependency on an external team to fix
