They are there, because test_cppcodecompletion has a more complex
duchain testing architecture, which includes support for preprocessor,
#included files, etc., which the one in test_duchain doesn't support.

The problem with both test_duchain and test_cppcodecompletion is that
they have an own replacement for the background parser and the whole
parsing architecture in kdevplatform/kdevelop, because that one didn't
support testing at that point.

However that problem has been fixed, and now we can use the _whole_
kdevplatform/kdevelop architecture for the tests, which is done in
test_cppcodegen, using the InsertIntoDUChain helper class, and in
long-term it might make sense to port the other tests to the same

Greetings, David
