Igniters, I've updated Ignite Coding Guidelines <https://cwiki.apache.org/confluence/display/IGNITE/Coding+Guidelines>. See 'TODOs', 'Commented out code' and 'Appendices\Broken tests' sections.
The main goal is to say about current approach to broken tests: instead of commenting out of broken test, we just mute them on TC. -- Artem --
