I would like to set up TFS 2013 so that TFSGroup1 (test) can only see bugs and TFSGroup2 (developers) can see product back log items and bugs. There is a request against this but it doesn't appear that there is an out of the box solution to this so I'm looking for the best work around.
My initial try at this was to use Areas - so that bugs would always be under the Test area and other PBIs would be under a number of other areas. Security could then be set appropriately against the work area node. Unfortunately new bugs cannot have a default are set (limitation of the template) even when editing them with witadmin.
I'm happy to upgrade to TFS 2015 if this has a better permissions model.
