I was looking into this over the course of pyOpenSci/software-submission#179, since it's difficult to tell how complete the test suite is without it. I tried adding the usual -fprofile-arcs -ftest-coverage build flags, but the coverage ends up being generated for the F90 files only. Not sure what the problem is.

Thank you, @dbaston for pinging this issue!
I've tried compiling using:

CMAKE_ARGS="-DCMAKE_CXX_FLAGS=-coverage -DCMAKE_C_FLAGS=-coverage -DCMAKE_Fortran_FLAGS=-coverage" pip install -e .

and it seems to work for both C++ and Fortran code:

Stay tuned for a proper codecov automation.
