This but let's also define debugging. From reading some of the comments left throughout the thread it seems like people don't think that a test failing and you having to go back and fix code (or even the test) is debugging but IMO it is. There is a bug, you are going back, finding it and fixing it. It usually means it is easier and faster to find/fix, but it is still time spent "debugging". I spend more time creating then debugging when I write the code from scratch, but I still say I spend probably at most 70% coding if it is a new project. The rest is in failing tests and finding those weird screwed up errors that take multiple days of a debugging session to find. For existing code I take over, it is probably usually more like a max of 50-60% coding depending on the original authors skill.
