We want to use the Test workflow to accomodate large teams with multiple workstreams that need to conduct testing. I created a rule that makes all of the details of the step case read only if the Phase is New or In Design and the current user is not the Designer, Author, or Owner. This works only for the details though. I would like to apply the same rule to the test steps and data table information so until the test is out of the design phase, no on but the author could edit it. I don't see a way to do this with the current rules set.
This would also help us create a rule making a test case read only once the Phase = Obsolete.
