git-history-coverage - summarise test coverage for recent git commits
git-history-coverage [options] rev-list
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.
--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.
