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).
