Create Unit Tests: Absolute path still hardcoded

[diethardsteiner]

I had troubles running unit tests across different environments and it turns out it's because the path to the ktr in the unit test xml is hardcode, even if I use ${UNIT_TESTS_BASE_PATH} via the setup dialog. If I define ${UNIT_TESTS_BASE_PATH}, I want this to be written to the xml file - unless I am doing something wrong here and there is already a better way in place.

As a workaround I currently edit the XML file manually and change the absolute path to a relative one.
