Git Bisect in Git & GitHub
git bisect does binary search through commits to find which one introduced a bug. You mark commits as "good" or "bad", and Git narrows down the culprit automatically. Useful when a bug appeared but you don't know which commit caused it.
Scenario: the app worked 10 commits ago but is broken now. Instead of manually checking each commit, bisect finds the exact commit that broke it.
Priya notices the login is broken but doesn't know when it broke. Arjun uses git bisect to narrow down which of 30 commits is the culprit in about 5 checks.
Git Bisect — Syntax
git bisect start git bisect bad HEAD # Mark current commit as bad git bisect good <good-commit> # Mark an earlier commit as good # Git checks out a commit in between for testing git bisect bad / git bisect good # Mark each as bad/good # Repeat until Git finds the culprit git bisect
