Exclusion markers for gcov

问题:

I'm using gcov to measure coverage in my C++ code.

I'd like to be able to mark certain lines of source code so that they are excluded from coverage reporting when using gcovr. I know they exist because I stumbled across them once but now I can't find where I saw them.

I'm not using lcov to report coverage so references to such markers are no good to me.

Can anyone point me to the right place?

TIA

回答1:

I figured this out finally. The lcov exclusion markers are valid with gcovr.

The following markers are recognized by geninfo:

  • LCOV_EXCL_LINE
    • Lines containing this marker will be excluded.
  • LCOV_EXCL_START
    • Marks the beginning of an excluded section. The current line is part of this section.
  • LCOV_EXCL_STOP
    • Marks the end of an excluded section. The current line not part of this section.

You can also replace 'LCOV' above with 'GCOV' or 'GCOVR'. They all work.
