I'm more on Marcus side here. Currently we don't have a single line of
c++ in our cmake file, and I don't see us inlining complex c++ code
either. So either the test consists of 1 or  2 lines which are faster
to write from scratch anyway, or it consists of complex non trivial
code and then better not inline it but put it in a separate file.
