Summary

• Bisection typically focuses on identifying a single commit via a Boolean test

• When you have a series of failures, you may need more information

  • Full test output, not just PASS/FAIL

  • Way to reduce test output to a value which can be argument in Boolean comparison

  • All commits where test output changed

• You need multiple bisection ("multisection")

• Devel-Git-MultiBisect provides that for Perl 5 core and CPAN distributions
