Debugging Tips
The following tips will make your life much easier when debugging:
- Before starting to debug, be clear about what the problem is. Make sure that you get all of the necessary information from the user as to what he did to generate the problem. Without this vital information, you can spend countless hours trying to reproduce the problem rather than solve it.
- Make changes one line of code at a time. I have seen many hot-shot developers attempt to change multiple lines of code simultaneously. Instead of correcting the problem they initially set out to solve, they generate a multitude of additional problems.
- Talk the problem out with other developers. Sometimes the process of simply verbalizing the problem can be enough to help you to figure it out. If verbalizing the problem doesn't provide you with the answer, the person that you are verbalizing to might know the answer.
- When all else fails, take a break. Many times I have stayed up into the wee hours of the night, attempting to solve a problem. After finally giving up, I surrender and go to bed. It's amazing how many times I solve the "unsolvable" problem from the night before while in the shower the next morning!
