Question

i am currently switching to funit to fully test my rather big Fortran-Project.
Is there a tool that allows me to find out which lines of my project were not
yet tested? I use emacs, so is there a simple script that would allow me to
easily see which parts of my file are not yet tested?

I could imagine recruiting the -prof compiler for something like that, but
i am just starting out. So i definitely cannot do this on my own.

Depends on your compiler. I use Intel Fortran on Linux for testing purposes, and its coverage checking options. Compile and link your code with something like

ifort -g -prof-gen=srcpos ...

(Side note: parallel make does not work for me with -prof-gen option enabled) The compilation will produce some extra files in your sources directory. Run the tests, each program execution will produce a *.dyn file in you sources directory. After running all the tests execute

profmerge
proforder
codecov

This will produce a nice detailed HTML-formatted coverage report. Don’t forget to delete old *.dyn and pgopti.dpi* files before running new series of tests, otherwise you will see an intersection of different coverage results.
