Code Walk Throughs

• Another commonly used testing mechanism is a code walk through.
• Another programmer walks through your code and tries to understand it.
• You can explain it to them, but they should be able to read the comments to understand it.
• This helps by spreading the knowledge, someone else knows how it works.
• It helps because you can maintain standards (like variable naming conventions).
• It helps because another set of eyes can find bugs you didn't consider.
• Mostly it helps because you know your not done until you can defend your code to someone else.
