git bisect Demo repo

Simple "fizzbuzz" project to demonstrate how to use git bisect.

How to use git bisect

Start the git bisect session and mark the good/bad commits

git checkout main
## copy the test file (git will remove the file so you need an untracked copy)
cp bisect_tests.example.py bisect_tests.py
git bisect start
git bisect bad
git bisect good 32558cc

With an active bisect session you can now start testing

## Run the tests
python bisect_tests.py

Any time the tests fail run git bisect bad and anytime the tests pass run git bisect good. Eventually you should find the first bad commit.

How to run the git bisect run demo

./set_bisect.sh
git bisect run ./bisect_test.sh

After running the above commands you should be checked out to the bad commit.

NOTE: Two new files are created for this demo. Git deletes any tracked files as it checks out commits so the test script and python tests need to be untracked to work

Run the slides in your browser (using reveal.js)

cd slides
python3 -m http.server
## OR
python -m SimpleHTTPServer
