Sorry if something like this has already been asked but I couldnt find it.
We know how ninjas can go from the academy to genin and from genin to chuunin through various tests and whatnot.

Im wondering if there is any indication of a jounin test because im wondering how neji, temari, and kankuro actually became a jounin during the time jump.

...unless theres nothing on the subject so far and its up to our imaginations...
