@AnttiKauppila @michalpasztamobica @jamesbeyond
It won't work this way. -r pattern is used to filter both test names and source files for coverage report. Coverage filtering will work only when filter pattern will match both test name and tested feature source file name.

@maciejbocianski , that explains why Seppo called his tests moduletest.cpp. I guess we need to rename ours.
