* source.extension.vsixmanifest has a reference to this project. that does the deployment of the dll. 
   Under Assets with a type of `UnitTestExtension`

* TestDiscoverer relies on a file called `(exe).is_unreal_test existing`.
   The TestTargetRules currently outputs this file
   The reason for this is to quickly identify text executables. 
   Another option would be add a special string into the exe and then look for it in the binary

#Debugging
