Simple example creating a code coverage report.
Checkout the repo and run the make command.
$ make
# clean up
rm -f *.o *.gcda *.gcno coverage.html module_tests
# compile with special flags
gcc -c -fprofile-arcs -ftest-coverage module_tests.c -o module_tests.o
# link with gcov
gcc module_tests.o -lgcov -o module_tests
# run tests
./module_tests
# run coverage report
gcovr -r . -s
