Git is a powerful tool. Once you’ve mastered
merge, there are endless possibilities. A very useful one is
git-bisect. It helps you find a commit that introduced a certain change in behavior.
git-bisect a lot in the Node.js project. The Node.js project has good continuous integration but some bugs are only discovered after a release. With
git-bisect, it’s easy to find the bad commit.
If you want to try out
git-bisect, here is a demo repository. At some point, a bug was introduced as you can see by running
npx mocha test1.js. Can you find the bad commit?
Instead of testing each step manually, you can run
git-bisect with a script. It will use the script at each step and automatically mark the commit, until it finds the first bad commit.
