I initially considered putting it in ports just for that reason. But it's too tightly coupled to src. The tests need to change with every feature addition or bug fix to src. If the tests lived in ports, then they would have to be aware of all of the differences between main, stable/14, stable/13, releng/13.2, etc. Updates to src would have to be synchronized with updates to ports, and the package builders introduce a few days' lag. I thought that synchronization effort would be too great. That's why I put the tests in src and used C++.
