And I feel bad when people do not react to received messages at all. feedback is important
Unit-testing tools that let the programmer sidestep poor dependency management in the design waste a valuable source of feedback. When the developers eventually do need to address these design weaknesses to add some urgent feature, they will find it harder to do. The poor structure will have influenced other parts of the system that rely on it, and any understanding of the original intent will have evaporated. As with dirty pots and pans, it’s easier to get the grease off before it’s been baked in.
