generating branch coverage data for lcov
i'm trying to use lcov for code coverage metrics, but I cannot get branches coverage to work. Here's how i'm using it: g++ -ggdb3 --coverage src/read.c tests/test.cpp -o bin/test lcov --zerocounters --directory $PWD lcov --capture --initial --directory $PWD --output-file coverage_output ./bin/test lcov --no-checksum --directory $PWD --capture --output-file coverage_output genhtml --branch-coverage --highlight --legend --output-directory out coverage_output but i get: Overall coverage rate: lines......: 100.0% (60 of 60 lines) functions..: 100.0% (26 of 26 functions) branches...: no data found
