Grabbing Unity Objects via external applications

Hello there. I'm currently attempting to do some automated test cases for the project I'm working on. We use a windows machine that runs games through Unity. I've a test app that is a windows app, I'm able to grab objects in our WPF programs fine, but I am not able to grab the objects in anything Unity based, as it is all self contained. This proves extremely hindersome when it comes to doing any kind of testing on Unity projects. Is anybody aware of any way to allow a Windows app access to Unity's objects (so I can grab object.size, etc.) in external applications?
