I have spent so much of my career debugging code, whether its Production code in a large scale enterprise applications or in my own personal code. Every time I start debugging I treat it as a murder mystery. I follow the same 6 steps to almost all of my debugging as it allows maximum throughput for me.
- Figure Out What Changed.
- Eliminate One Possibility Each Time.
- Focus on code changes.
- Use the Google.
- Take Notes and Share New Information.
- Pay Attention to other Developers Suggestions.
Sometimes you can skip some steps but the first 2 are must do's if you can narrow down to a single change in file a, then you know file a introduced the bug.If you have multiple changes elimating each change will allow you to swiftly move through the issue and come to a solution.
I followed this idea for years and it has never let me down, next time you are debugging try thinking it's a murder mystery!
