git bisect kata

git bisect commands

• git bisect start - start, either of below will do it so it's unnecessary
• git bisect bad - mark current commit bad and jump to next one
• git bisect good - mark current commit ok and jump
• git bisect reset - start over

About

The latest commit in this repo is definitely broken, we can test this by running ./cat.py. A red cat is wrong, yellow is ok. The first is definitely ok, you can jump to the first commit by

git checkout 4a37fe34508f8cae5befa620e284343f61256cdb
# or by tag
git checkout start

Now, using bisect find who broke the code.

The flow

• clone the repo, you're on newest commit, run the test (cat.py), the cat is red so mark it bad.
• go to the first commit, run the test, the cat is ok, mark it good.
• git will jump now to some commit, run the test and mark it good or bad, until you find the answer.

The goal

To find the name of the committer who made the cat red.
