Exclusion Markers

You can exclude parts of your code from coverage metrics.

  • If GCOVR_EXCL_LINE appears within a line, that line is ignored.
  • If GCOVR_EXCL_START appears within a line, all following lines (including the current line) are ignored until a GCOVR_EXCL_STOP marker is encountered.

Instead of GCOVR_*, the markers may also start with GCOV_* or LCOV_*. However, start and stop markers must use the same style. The prefix is configurable with the option --exclude-pattern-prefix.

In the excluded regions, any coverage is excluded. It is not currently possible to exclude only branch coverage in that region. In particular, lcov’s EXCL_BR markers are not supported (see issue #%s121).
