I’ll agree that testing is just a tool. Even the best tool will not help if not applied properly. Testing probably won’t make up for poor development skills. But, as someone who has been using rails testing for a short time now, I believe it to be a very valuable tool. I find that testing before and after each change I make has helped me catch mistakes quickly. This, ( along wth SVN), has been especially useful during long programming sessions when the mind starts to get dull. I’m sure as my understanding of rails testing improves, my software quality will improve as well. I look forward to the journey.
