c++ - How to tell lcov to ignore lines in the source files -

i wondering if there possibility tell lcov ignore lines in source files, ie. not report them unvisited. looking solution can put in code itself, like:

int some_method(char some_var, char some_other_var) {     if(some_var == 'a')     {          if(some_other_var == 'b')          {                /* real stuff here */          }          else          {                 lcov_do_not_report_next_line // **<-- this?? **                 not_implemented("a*")          }     }     else     {          not_implemented("*")     } 

and necessary background:

a big piece of code 1 above being tested in series of unit tests, since code still under development there lot of not_implemented("a*") macros put message on screen line number/filename , exit application. there no tests not implemented branches, written when feature implemented.

however lcov reports these not_implemented lines , ugly in coverage report (ie: make high ratio of red lines).

is ask possible, or should live this?

you can use following comments in source.

from http://ltp.sourceforge.net/coverage/lcov/geninfo.1.php

• lcov_excl_line
  • lines containing marker excluded.
• lcov_excl_start
  • marks beginning of excluded section. current line part of section.
• lcov_excl_stop
  • marks end of excluded section. current line not part of section.
