Re: How to disable Test resources module for users?
Through group you could just forbid all actions for some user. But module will be visible.
Predefined groups couldn't be customized, thus you should create your new one (yes, in the tools-customize [img]/images/graemlins/smile.gif[/img] ). Note that new group is quite heavy operation for the DB, so "play" with setupping on the clear project without business-sensative data.
then you should go to the Change button and uncheck all items for Test Resources tab. Or even setup data hiding filter.
