NAME

       git-history-coverage - summarise test coverage for recent git commits

SYNOPSIS

       git-history-coverage [options] rev-list

DESCRIPTION

       Git-history-coverage  extracts  test  coverage  data  produced  by  C  and C++ programs compiled with gcc
       --coverage, and correlates it to git commits, printing a coverage summary which  shows  how  well  tested
       recent code changes have been.  This is useful for nightly builds and Continuous Integration systems such
       as Jenkins.

       For  the output of git-history-coverage to make any sense, the coverage data must be generated by running
       code which corresponds to the last commit in the range specified by rev-list.

       When used without any options, git-history-coverage prints three summaries.

       overall
              A summary of all the commits specified by rev-list.

       by author
              A summary split up by each author represented in the set of commits specified by rev-list.

       by commit
              A summary for each individual commit in the set of commits specified by rev-list.

       For each of these summaries, git-history-coverage prints statistics showing how many lines of  code  were
       in  the  commits,  how  many  lines  represent  executable  code  (as  opposed to comments, test code, or
       infrastructure like Makefiles), and how many lines were actually executed in tests.

OPTIONS

       --summary-overall
              Print the overall summary (with no options, all three summaries are printed).

       --summary-by-author
              Print the by author summary (with no options, all three summaries are printed).

       --summary-by-commit
              Print the by commit summary (with no options, all three summaries are printed).

       --gcda-prefix=dir
              Look for .gcda files underneath the directory dir.  This option is used to read  runtime  coverage
              information written when a test program is run using the same --gcda-prefix option to ggcov-run.
