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.
