make sure posts are collapsed when there is something in the body (i check if it has at least 50 chars of html code), it's read and it has at least 1 comment
make sure all read comments are collapsed when opening a post
make sure new comments are never collapsed
if a thread is new the NEW tag is visible only on the root comment
if more than 1 replies are new make sure all of them have the NEW tag
check green bg has some space btw replies
open a post with some new comments
check a thread is marked as read when you reply
check a single comment is marked as read when you react to it
check new comments are still NEW when a new comment comes in
check new comments are still NEW when you add a reply
check new comments are not new after you go back and reopen the post
regression test: make sure your replies are not collapsed/hidden when a comment comes in live
