[MTP] TestNodeOutputMessage / TestNodeErrorMessage

[thomhurst]

Currently, as far as I'm aware there isn't a way to stream output to IDEs? There are standard output and error messages properties that you can attach to a test node when it completes.

Would it make sense to be able to publish a new message for output or error, containing the test node id and the message. Then the ide can subscribe to it and append them to the output window. This way hanging or long running tests can show output which can be useful to the user.

Messages sent through output device should be forwarded to the IDE, at least starting from #4178. Could you try with latest 1.5.3 and let us know?

Ah I'll take a look.

Unfortunately I need to wait for Rider to release a fix before I can upgrade users as something in 1.5.0 onwards broke test discovery: https://youtrack.jetbrains.com/issue/RSRP-499756/Package-Microsoft.Testing.Platform.MSBuild-1.5.0-breaks-test-discovery
