Doxygen will only process files with a @file documentation comment. Up to now, none of our test code has such a comment, preventing the cross-links to unit tests from working. This is unfortunate, since unit tests, and even the code comments there, can be considered as the most useful form of technical documentation. Thus I'll start an initiative to fill in those missing comments automatically
