dotnet test output can be hard to navigate

[Youssef1313]

I came across a case in microsoft/testfx where I ended up with one projects not installing hangdump extension. And it was failing with:

  Unknown option '--hangdump'
  Unknown option '--hangdump-timeout'

The above error was buried in the middle of the big output of dotnet test.

The output summary near the end was only this:

FYI @nohwnd

[nohwnd]

Looks like they are not even part of the summary, that is a problem.

[Youssef1313]

Yes. The TerminalTestReporter is only aware of processes that handshaked with dotnet test.

sdk/src/Cli/dotnet/Commands/Test/MTP/TestApplicationHandler.cs

Line 70 in f578225

_output.AssemblyRunStarted(_module.TargetPath, handshakeInfo.TargetFramework, handshakeInfo.Architecture, handshakeInfo.ExecutionId, instanceId);

Any other failures are buried in the middle in the output and are extremely difficult to find.
