It is good to have an standardized way to run builds and tests on the repository
of a project, so that you can find when a bug was introduced by using
git bisect run.
I’ve already been in the situation when a bug was introduced and I didn’t know how it even was occurring, and running Git bisect over hundreds of commits to pinpoint the failing commit was very empowering:
Git will than do a binary search between the commits, and run the commands you provide it with to find the failing commit.
Instead of being afraid of doing a bisect, you should instead leverage it, and make Git help you dig through the history of the repository to find the bad code.
