Currently, the ui-automation tag on Stack Overflow has a description that indicates it is for the Microsoft UI Automation Framework. However, there is a scripting tool within Apple's Instruments package that is also called UI Automation. There are a significant number of questions regarding the writing of scripts for testing of applications within the ui-automation tag, as can be seen here and here.
It's not obvious to people asking questions about the UI Automation instrument that they should be thinking about it as iOS UI Automation, so I believe people will keep tagging their non-Microsoft UI Automation questions in this manner. It would seem to me that adding the appropriate platform-specific tags like ios would make it clear what the question was referring to.
Would expanding the definition of the UI Automation tag wiki to include this other tool be a more appropriate course, or is retagging to a more specific term as is currently being done preferred?
