NAME Devel::Git::MultiBisect - Study test output over a range of git commits DESCRIPTION Given a Perl library or application kept in git for version control, it is often useful to be able to compare the output collected from running one or several test files over a range of git commits. If that range is sufficiently large, a test may fail in more than one way over that range. If that is the case, then simply asking, *"When did this file start to fail?"* is insufficient. We may want to (a) capture the test output for each commit; or, (b) capture the test output only at those commits where the output changed. The output of a run of a test file may change for a variety of reasons: test failures, segfaults, changes in the number or content of tests, etc.) Devel::Git::MultiBisect provides methods to achieve that objective. Its child classes, Devel::Git::MultiBisect::AllCommits and Devel::Git::MultiBisect::Transitions, provide different flavors of that functionality for objectives (a) and (b), respectively. Please refer to their documentation for further discussion. PREREQUISITES Perl 5.10 or higher. Capture::Tiny and IO::CaptureOutput needed for testing only. git.
