Last week there was some user feedback about the possibilties to configure test source folder.
This weekend during napping I had the idea how to implement this feature request.
After some hours of work I have created a new property page which shows the test source folder (as preferences are not adapted yet for the new feature this page shows all source folder of the underlying project). Additionally I started a wizard for the unit source folder selection.
I learned a lot of stuff about JFace and this was really fun :-) (I'm hoping to find some more freetime to work an this soon)
