git bisect

Use binary search to find the commit that introduced a bug.

Git automatically jumps back and forth in the commit graph to progressively narrow down the faulty commit.

Start a bisect session on a commit range bounded by a known buggy commit, and a known clean (typically older) one:

git bisect start {bad_commit} {good_commit}

For each commit that `git bisect` selects, mark it as "bad" or "good" after testing it for the issue:

git bisect {good|bad}

After `git bisect` pinpoints the faulty commit, end the bisect session and return to the previous branch:

git bisect reset

Skip a commit during a bisect (e.g. one that fails the tests due to a different issue):

git bisect skip
