Git Merge Conflict Simulator

Overview

The Git Merge Conflict Simulator provides a safe environment to practice resolving merge conflicts before encountering them in real projects. Modify code in two different branches, trigger a conflict, and learn how to interpret Git’s conflict markers (<<<<<<<, =======, >>>>>>>). Practice the resolution process interactively without risking your actual codebase.

Tips

• Make sure to remove ALL conflict markers (<<<<<<<, =======, >>>>>>>) when resolving - leaving any behind will break your code
• You have three resolution strategies: keep one version, combine both intelligently, or write entirely new code that supersedes both
• The code between <<<<<<< HEAD and ======= is from your current branch, code between ======= and >>>>>>> is from the incoming branch
• Communicate with teammates when resolving conflicts involving their code - they may have context about why they made their changes
• After resolving, always test your code to ensure the resolution works correctly and doesn’t introduce bugs
• In real Git, use git status to see which files have conflicts, then resolve them one at a time
• Practice creating intentional conflicts in the simulator to build confidence before facing them in production work
