New test result state: "warning" (⚠️)

[matepek]

I would use it to mark some tests which are not failed but wrote some mentionable comment to the user. It could be something like this ⚠️.

(I also would like to provide an option to my users to categorise some of the messages.)

This extension also could provide one option like: "treatWarningAsSuccess" and the counterpart.

Let me know if it is not clear.

Bests,
