In this project, we'll learn how to track down bugs in a codebase using Git bisect, a powerful binary search tool that pinpoints the exact commit that introduced a bug. When working with repositories containing hundreds or thousands of commits, manually checking each one is impractical. Git bisect automates this process by efficiently narrowing down the problematic commit through binary search algorithms, cutting debugging time from hours to minutes.
We'll start by marking known good and bad commits to establish the search boundaries, then guide Git through a binary search process by testing intermediate commits and marking them as good or bad. We'll explore Git logs to understand the bisect history and identify the culprit commit. Next, we'll write a Bash script that runs automated tests using Apache Maven, then integrate this script with Git bisect automation to eliminate manual testing at each step. This automated bisect workflow tests each commit automatically and identifies the bug source without human intervention.
By the end, we'll have mastered Git bisect for bug tracking, version control debugging, automated testing with Bash scripts, and binary search techniques for efficient code history analysis applicable to any software development project with Git repositories.
